Which number is a prime number that is greater than 10?

A prime number is defined as a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In other words, prime numbers have exactly two distinct positive divisors: 1 and the number itself.

Looking at the options provided, 13 is the only number that meets the criteria of being a prime number greater than 10. It is only divisible by 1 and itself (13), confirming its status as a prime number.

The other numbers listed do not qualify as prime. For example, 12 is divisible by 1, 2, 3, 4, 6, and 12, giving it more than two divisors. The same applies to 8, which can be divided by 1, 2, 4, and 8, also disqualifying it as prime. Lastly, 9 is divisible by 1, 3, and 9, therefore it too is not a prime number. Thus, the correct response is indeed 13.
