How many positive integer factors does k have?
(1) k has the same number of positive integer factors as \(3^3\) --> 3^3 has 4 factors, so k also has 4 factors. Sufficient.
(2) k=rs, where r and s are different prime numbers --> since r and s are primes then k has (1+1)(1+1)=4 factors. Sufficient.
Answer: D.
