To answer this question, let's go through each option and determine whether it falls within the given postal rates:

Option A) 0, 9, 19, 49, 50, 74, 75, 99, 100

• The postal rates are $0.25 up to 10 grams, $0.35 up to 50 grams, $0.45 up to 75 grams, and $0.55 up to 100 grams.
• Option A includes weights that are not within the given ranges, such as 9 grams and 19 grams. Therefore, this option is incorrect.

Option B) 10, 50, 75, 100, 250, 1000

• Option B includes weights that are not within the given ranges, such as 250 grams and 1000 grams. Therefore, this option is incorrect.

Option C) 0, 1, 10, 11, 50, 51, 75, 76, 100, 101

• The postal rates are $0.25 up to 10 grams, $0.35 up to 50 grams, $0.45 up to 75 grams, and $0.55 up to 100 grams.
• Option C includes weights that fall within the given ranges, such as 10 grams, 50 grams, 75 grams, and 100 grams. Therefore, this option is correct.

Option D) 25, 26, 35, 36, 45, 46, 55, 56

• Option D includes weights that are not within the given ranges, such as 25 grams and 35 grams. Therefore, this option is incorrect.

The correct answer is Option C. This option is correct because it includes weights that fall within the given postal rates.

To assess the coverage achieved for structure-based (white-box) test techniques, we need to consider which aspects of the structure have been exercised. Let's go through each option to understand which ones are correct:

Option A) V, W or Y - This option is incorrect because it includes option V, which refers to "Decision Outcomes Exercised." Decision outcomes are typically associated with black-box testing techniques, not structure-based (white-box) testing.

Option B) W, X or Y - This option is incorrect because it includes option X, which refers to "Boundaries Exercised." While boundary testing is commonly used in structure-based testing, it alone does not represent the coverage achieved by structure-based techniques.

Option C) V, Y or Z - This option is correct because it includes options Y and Z, which are both applicable to structure-based testing. "Conditions or multiple conditions exercised" (option Y) and "Statements Exercised" (option Z) are key elements to consider when assessing the coverage achieved by structure-based testing.

Option D) W, X or Z - This option is incorrect because it includes option W, which refers to "Partitions Exercised." Partitions are commonly associated with equivalence partitioning, which is a black-box testing technique, not structure-based testing.

Therefore, the correct answer is C. This option includes the aspects relevant to assessing coverage achieved by structure-based (white-box) test techniques.

To answer this question, we need to understand the characteristics of poor software.

Option A) Only Project Risks - This option is incorrect. Poor software characteristics are not limited to project risks alone. There are other factors that contribute to poor software.

Option B) Only Product Risks - This option is correct. Poor software characteristics primarily refer to risks or issues related to the product itself. This can include bugs, crashes, security vulnerabilities, poor performance, and usability issues.

Option C) Project Risks and Product Risks - This option is incorrect. While project risks can contribute to poor software, the main focus is on the product itself.

Option D) Project Risks or Product Risks - This option is incorrect. Poor software characteristics typically refer to product risks, but it doesn't exclude the possibility of project risks contributing to poor software as well.

The correct answer is B) Only Product Risks. This option is correct because poor software characteristics primarily refer to risks or issues related to the product itself.
