Took me less than 1 min.
A,C and E can be taken right out for if you have an even number, they will all yield an even answer
B can be taken out because if you put in an odd number, the first term will be odd, the second even and the third odd. odd+even+odd = even number.
Only D stand

n^2 + n = 0 (2)

1. n + 2
2. n + 3
3. 2n + 2
4. 2n + 1
5. 5n + 6

Of all, the fourth one is odd, irrespective of what n is.
