I think the answer is highlight%28C.++36%29. Here's the logic:
A. 12 = 12 / 2 * 2 (even number of operations, so in 60 operations we can also reach 12)
B. 18 = 12 / 2 * 3 (even)
C. 36 = 12 /2 * 3 * 2 (it takes an odd number of operations to go from 12 to 36)
D. 72 = 12 * 2 * 3 (even)
E. 108 = 12 * 3 * 3 (even)
