Since T is divisible by 12. Let's assume T to be 12. Then, T2 =144. Then the minimum value for which T2 is not an integer when divided by 2^a is when a=5. Hence D is the answer.

Explanation
If t is divisible by 12, then t2 must be divisible by 144 or 2×2×2×2×3×3. Therefore, t2 can be divided evenly by 2 at least four times, so a must be at least 5 before t22a might not be an integer.

If t is divisible by 12 and we need to find the least possible integer value of a for which t^2/2^a might not be an integer So, we need to take the smallest possible positive value of t [positive as 0 is divisible by all numbers so it will be divisible by all values of 2^a] => t = 12 = 22∗3 Now, t2 = (22∗3)^2 = 24∗32 So min value of a for which t2 might not be an integer will be 5
