For n to meet (2), n can only be odd.

I say (B)

1) n = 3*k where k is itenger
k : odd > n is odd
k : even > n is even

Not Sufficient

2) The only cases that 2n is divisible by twice as many positive integers as n are for prime numbers without 2.
As all prime number except 2 are odds, thus n must be odd.

Sufficient
