Stmt 1: INSUFFICIENT as n can be 1 or 2; as 1^4
Stmt 2: INSUFFICIENT as it does not tell us anything about n just that n is not n^2
Stmt 1 and Stmt 2 together concludes for us that n is 2 therefore C

(1) first find what possible values of n^4 would fall less than 25
1^4 = 1
2^4 = 16
3^4 = 81
So n can be 1 or 2, insufficient

(2) still doesn't tell us much other than n is not equal to its square, insufficient

if we put (1) and (2) together, we can know that n cannot be 1, so n can only be 2. SUFFICIENT
