All of the choices are factors of 72 (you can divide them into 72 without getting a remainder), but from that list, c. 2 is the only one that is a prime number.

I hope this helps!

2 is the only prime in the list and 2 is a factor 0f 72,
so the answer is c.

72/4 = 18
72/9 = 8
72/2 = 36
72/12 = 6

All of them are factors of 72 but 2 is its prime factor.
