Because.. 2 is even but prime. so A can't be the ans.

from statements 1 and 2, you can tell that the number must not be a prime since no even number is a prime, except 2. Thus, C should be the answer

C.
A says that x is even, so it could be any even #. 2 is even and prime but 4,6,8 is even and not prime.. Not sufficient B says that any integer between 2 and 19.. 3 is prime but 4 is not prime. Combining A and B  4,6,8,10,12,14,16,18 none of them are prime.
