The product of two composite numbers is between 11 and 17.

12 = 2 x 2 x 3, so it cannot be the product of two composite numbers, because there are only three prime factors.

13 is prime.

14 = 2 x 7, so it cannot be the number.

15 = 3 x 5, so it cannot be the number.

16 = 2 x 2 x 2 x 2, so it is the product of two composite numbers, 4 x 4.

16 is the only number that fits. Its prime factors are 2, 2, 2, and 2.
