If x and y are even integers, which of the following is an odd integer? Choose the correct choice from the following choices:
A) xy + 2
B) x(y − 1)
C) x(x + 5)
D) 3x + 4y
E) (x + 3)(y − 1)
If x and y are even integers, then:   A. xy + 2: even + even = even   B. x(y − 1): even(odd) = even   C. x(x + 5): even(odd) = even   D. 3x + 4y: even + even = even   E. (x + 3)(y − 1): (odd)(odd) = odd.   Answer is (x + 3)(y − 1).
