12. The best answer is E. The area of the triangle is XY/2. Statement (1) tells us that X is a prime number, that can be even (2) or odd (3, 5, 7, etc.). Statement (2) tells us that Y is an odd integer. The multiplication of X and Y can be an odd number or an even number, thus we cannot determine if the area of the triangle is an integer or not.
