If a^2b = 12^2 and b is an odd integer, then a
could be divisible by all of the following
EXCEPT?
A 3 B 4 C 6 D 9 E 12

D

Explanation:

If b is 3 or 9 then a^2 becomes 4*4 or 3*4*4 and a would be either 4 or 4sqrt3

and a would not be divisible by 3,6,9, nor 12

However if the question were about a^2 and b were 3 then the answer would be only 9.
