well, though this question obviously contains errors...just try it anyway
A. 0 ---> no! coz a number is divisible by 12 cant be a prime

C. 2 ---> it should be even then--->can't be prime

D. 3 ---> no! coz if r= 3 --> the number = 12k +3 , which is divisible by 3, can't be a prime

B and E are possible choices.

sounds like the question should be divided by 2 instead of 12 if the answer is B.
