Evaluate each choice:
(A) 2(even) + 3(odd) − 1 = even + odd − odd = even
(B) 2(even) + 2(odd) − 2 = even + even − even = even
(C) 3(even) + 3(odd) + 1 = even + odd + odd = even
(D) 3(even) + 2(odd) + 2 = even + even + even = even
(E) 3(even) + 2(odd) + 1 = even + even + odd = odd
E is the answer
(A) 2(even) + 3(odd) − 1 = even + odd − odd = even
(B) 2(even) + 2(odd) − 2 = even + even − even = even
(C) 3(even) + 3(odd) + 1 = even + odd + odd = even
(D) 3(even) + 2(odd) + 2 = even + even + even = even
(E) 3(even) + 2(odd) + 1 = even + even + odd = odd
E is the answer
