Stock variable is defined as a variable which is measured at a particular point of time. Stock is not time dimensional. It influences the flow. Example: wealth, capital, etc.

Final goods include those goods which are either consumed by the households or purchased by the producers for investment purposes. 

If the end-use of the good is for further production or resale, then the good Is an intermediate good. However, if the end-use of the good is consumption or investment, then the good is a final good. 

Milk and Bread are examples of Non-durable good. Non-durable gods are those goods which are used-up in a single act of consumption. Bread and milk are used-up in a single act of consumption. The same milk or bread cannot be used again.

Household is the consumption sector. Household sector receive goods and services from the producer sector for consumption purpose and thus the household sector can be termed as the consumption sector. Households are also the owners of the factors of production.

Capital is not a flow. Capital falls under the stock concept since it relates to a point of time. Capital is not time dimensional. Capital is not related to a period of time like flow.

Wealth is a stock. Wealth falls under the stock concept since it relates to a point of time. Wealth is not time dimensional. Wealth is not related to a period of time like flow.

Refrigerator purchased by a confectionery shop is an example of intermediate good since refrigerator is not yet ready for use by the final users. Value is yet to be added. Refrigerator is used as a raw material by a confectionery shop.

Depreciation is a flow since it is measured over a specified period of time. It is time dimensional as it is generally measured over a year.

Foreign embassies in India are a part of India's geographical territory and not economic territory. For example: Embassy of USA in India is a  part of domestic territory of USA and a part of geographical territory of India.

Capital is a stock since it is measured at a point of time. Capital is not time dimensional. It is not measured over a specified period of time like flow. Therefore, capital is a stock concept.

Capital formation is measured over a period of time hence it is a flow concept.

The goods which are consumed by a consumer to satisfy his want is known as consumer goods, while goods used in a production process are intermediate goods. Hence, bread can either be a consumer good or an intermediate good based on its use.

Intermediate goods have a derived demand as their demand depends on demand for final goods.
On the other hand, final goods have a direct demand as they satisfy the wants directly.

A good can be an intermediate good as well as a final good, depending upon its nature of use.
For example, a car purchased by a household is a final good, whereas, It will be an intermediate good if it is purchased by a car dealer. 

Households and firms depend on each other in the circular flow of income in case of a two-sector model. Participants of the two-sector economy are households and producers.  Flow of money from producers to households as payments for the purchase of factor services has been a continuous process. So, there has been the flow of money from households to producers as payments for the purchase of consumer goods and services, This non-stop continuity of inter-sectoral flows is called 'circularity of flows'. Hence, total consumption by households is always equal to total production by the producers.

Both 'Expected Obsolescence' and 'Unexpected Obsolescence' are considered for determining the amount of depreciation- this is a false statement since only expected obsolescence is considered for determining the amount of depreciation. It has two components: loss of value of fixed assets due to change in technology and change in demand.

National wealth is not an example of flow variable. It is a stock since it is measured at a point of time. National wealth is not time dimensional. It is not measured over a specified period of time like flow. Therefore, national wealth is a stock concept.

Losses are classified as a flow variable since it is measured over a specified period of time. It is time dimensional as it is generally measured over a year.

Depreciation means loss of fixed assets overtime due to wear and tear. Depreciation is also called consumption of fixed capital. Loss of fixed assets happen on account of normal wear and tear, normal rate of accidental damages and expected obsolescence.

Final goods refer to those goods which are used either for consumption or for investment. Final goods have crossed the boundary of production and are ready for use by their final users. These goods are included in the estimation of national product or national income. Example: Bread and butter used by the consumers.

Sugar purchased by a Sweet shop is an intermediate good, while it is a final good when it is purchased by a consumer as sugar purchased by a sweet shop is used as a raw material and goods used for raw material are classified as intermediate goods as value is yet to be added, while, sugar purchased by a consumer is a final good as it is directly consumed and no value is yet to be added.

Depreciation of fixed capital assets refers to normal wear and tear and foreseen obsolescence. Depreciation is also called consumption of fixed capital. Loss of fixed assets happen on account of normal wear and tear, normal rate of accidental damages and expected obsolescence.

Goods purchased for the following purpose are final goods:
a) For satisfaction of wants
b) For investment in firm
Final goods are those goods which crossed the boundary of production and are ready to use by their final users, Final goods must lead to either final consumption expenditure or investment expenditure in the economy.

Unforeseen obsolescence of fixed capital assets during production is capital loss. Unforeseen obsolescence which may happen due to natural calamity is not taken into account while calculating depreciation and hence, it causes capital loss.

A frequently used tool that explains the relationship between the level of investment made in the economy and the consequent increase in GDP is the capital-output ratio. The concept of the capital-output ratio expresses the relationship between the value of capital invested and the value of output.

Capital output ratio is the amount of capital needed to produce one unit of output. For example, suppose that investment in an economy, investment is 32% (of GDP), and the economic growth corresponding to this level of investment is 8%.

Here, a Rs 32 investment produces an output of Rs 8. Capital output ratio is 32/8 or 4. In other words, to produce one unit of output, 4 unit of capital is needed. But don’t forget that the Rs 32 invested in the form of machinery will remain there for around ten or twelve years. Such machinery will be giving Rs 1 output in every year.

Hence, B is the correct option.

The Banking Codes and Standards Board of India (BCSBI) is an independent banking industry watchdog that protects consumers of banking services in India. The board oversee compliance with the "Code of Bank's Commitment to Customers".

Exports refer to the goods and services sold by domestic traders to foreign traders; the revenue thus generated is foreign trade revenue. Imports, on the other hand, refers to the purchases made by the domestic traders from foreign traders; which requires foreign trade payments.
Net exports will be positive when revenue from foreign trade is higher than payments, i.e., exports greater than imports.

Marginal efficiency of capital refers to the rate of return that is expected from an additional unit of investment made or capital utilised. The marginal efficiency of capital, thus, precisely represents the expected rate of return on investment.

Autonomous investment is done without taking into account the income of the investor or the profit that can be generated from investment. This type of investment is majorly done with the objective of public welfare or infrastructure development by the government or public sector.
