A prime number means that the number is only divisible by one and itself.
14 is a multiple of 2 and 7, so 14 wouldn't be it.
21 is a multiple of 3 and 7, so 21 wouldn't be it.
33 is a multiple of 3 and 11, so 33 wouldn't be it.
13 is only divisible by itself because no number can be multiplied to get 13.
So the correct answer is : 13 is the prime number.
