(A) 2n + 2
when n=0 it's even

(B) n – 5
when n=8 it's even

(C) 2n
always even

(D) 2n + 3
Always odd since even +odd = odd

(E) 5n + 2
when n=0 it's even

Therefore IMO E

(A) 2n + 2
even*n + even = even
(B) n – 5
Might be odd-odd = even
(C) 2n
even * n = even
(D) 2n + 3
even * n + odd = odd
(E) 5n + 2
Might be odd*even = even
