Hence, the correct answer is "39".

1. Prime Number: A prime number is a natural number greater than 1 that has only 2 factors: 1 and themselves. For example, the first 5 prime numbers are 2, 3, 5, 7, and 11. 

2. Composite Number: A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.
