If n is an integer, n is divisible by how many positive integers?

i) n is the product of two prime numbers
ii) n and 2^3 are each divisible by the same number of positive integers

OA: D

ii) i understand

but if i)

let prime numbers be 3,4, then there are 4 possible divisors (1,3,4,12)
but if the prime numbers are 1,2, then there are only 2 possible divisors (1,2)

anyone?

nm just realized that 1 is not a prime number.

4 and 1 are not prime numbers.

3,5 - (1,3,5,15)
5,7 - (1,5,7,35)
