B. All percentages of success should be multiples of 7. The given percentages cannot be correct.

C. All percentages of success should be multiples of 8. The given percentages cannot be correct.

D. All percentages of success should be multiples of 4. The given percentages cannot be correct.

Explanation / Answer

Solution:

option

A. All percentages of success should be multiples of 25. The given percentages cannot be correct.

The percentage of success is #successes/4, and since #success has to be an integer between 0 and 4, the possible values are 0/4=0, 1/4=25%, 2/4=50%, etc. up to 4/4=100%. All of these are multiples of 25.
