Explanation

Boundary value analysis tests at boundaries and just beyond them. For postal rates at 10, 50, 75, and 100 grams, we need values at each boundary: 0 and 1 (below 10), 10 and 11 (at/beyond 10), 50 and 51 (at/beyond 50), 75 and 76 (at/beyond 75), 100 and 101 (at/beyond 100). Option C covers all 11 critical test points.

AI explanation

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.
