Correct Answer: DFor values to be in different equivalence partitions, each value must belong to a different range specified. The given ranges are Fail (0-39), Pass (40-59), Merit (60-79), and Distinction (80-100). Option D includes 25 (Fail), 39 (Fail), 60 (Merit), and 81 (Distinction). However, for a correct answer, no two values should belong to the same equivalence partition. Upon re-evaluating the options, it seems Option B correctly spans each range: 0 (Fail), 45 (Pass), 79 (Merit), and 87 (Distinction). Therefore, Option B is accurate as it represents values from different equivalence partitions.
