Let x, y and z be distinct integers, x and y are odd and positive, and z is even and
positive. Which one of the following statements cannot be true?
Choose the correct choice from the following answers:
A) (x – z)^2 * y is even
B) (x – z)*y^2 is odd
C) (x – z)*y is odd
D) (x – y)^2 * z is even
E) none
Explanation :   Let x = 5, y= 3, z = 2 (according to the given condition)   (x – z)2 * y :- ( 5 - 2)2 * 3 = 27   (x – z) * y2 :- (5 - 2) * 32 = 27   (x – z) * y :- (5 - 2) * 3 = 9.   (x – y)2 * z :- (5 - 3)2 * 2 = 8.   (x – z)^2 * y is evennswer : (x – z)^2 * y is even
