The question is, "All numbers divisible by 16 and 12 are also divisible by which of the following?"

Aside from the obviously wrong choices 31, 43, and 46, the list contains two choices which could be correct but only one is accepted as the "correct" answer.

The correct answer is said to be 24, but 32 is also an available choice. If a number is divisible by 16, then it must also be divisible by 32. I see no reason why 24 should be considered a correct answer but not 32.
