How many different prime factors contribute to the form the positive integer n ?

St1] Four different prime numbers are factors of 2 n.
This means that the prime number 2 either could be a part of 'n' itself, yeilding 4 as the answer or could not be a part of 'n' yeilding 3 as the answer. Insuff.

St2] Four different prime numbers are factors of n^2.
If 4 different prime numbers make up n^2, then all 4 must be present in 'n' as well. Suff.

I pick B.
