A hill always has

  1. Trees

  2. Height

  3. Animals

  4. Water


Correct Option: B

AI Explanation

To answer this question, you need to understand the characteristics of a hill. Let's go through each option to understand why it is correct or incorrect:

Option A) Trees - This option is incorrect because not all hills have trees. While some hills may have trees growing on them, it is not a defining characteristic of a hill.

Option B) Height - This option is correct because a hill is defined as a naturally raised area of land that is higher than the surrounding terrain. Therefore, height is an essential characteristic of a hill.

Option C) Animals - This option is incorrect because the presence of animals is not a defining characteristic of a hill. Animals may inhabit hills, but their presence is not necessary for it to be considered a hill.

Option D) Water - This option is incorrect because the presence of water is not a defining characteristic of a hill. While hills may have rivers or lakes nearby, the presence of water itself does not determine whether an area is a hill.

The correct answer is Option B) Height. This option is correct because the defining characteristic of a hill is its elevation or height, being higher than the surrounding terrain.

  4. Coercion


Correct Option: A

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Regulation - This option is correct because management involves creating and enforcing rules, policies, and procedures to ensure that organizational goals are achieved. Regulation helps maintain order, consistency, and compliance within the organization.

Option B) Exhortation - This option is incorrect. While management may involve motivating and inspiring employees to perform better, exhortation alone is not enough to encompass the entire scope of management.

Option C) Counsel - This option is incorrect. While management may involve providing guidance, advice, and support to employees, counsel alone does not capture the full range of activities involved in management.

Option D) Coercion - This option is incorrect. Coercion refers to the use of force or threats to make someone do something against their will. Effective management is based on voluntary cooperation and motivation rather than coercion.

The correct answer is A) Regulation. This option is correct because management involves creating and enforcing rules, policies, and procedures to ensure that organizational goals are achieved.
