Actually, you're correct.

If you combine the statements, n could be any multiple of 12. 12 is not divisible by 24, but 24 is, so the statements combined are insufficient.

This is an Official Guide question. The answer is definitely E. Go back and double-check. For future reference, make sure you copy all problems and solutions exactly as written in the materials.
