What is the next prime number after 7?

• A. 9
• B. 10
• C. 11
• D. 12

Answer: (C)

The next prime number after 7 is 11. A prime number is defined as a natural number greater than 1 that has no positive divisors other than 1 and itself. Starting from 8, which is the number immediately following 7, we can analyze the subsequent numbers. Both 8 and 9 are composite numbers: 8 can be divided by 1, 2, 4, and itself (8), while 9 can be divided by 1, 3, and itself (9). The number 10 is also composite, as it can be divided by 1, 2, 5, and itself (10). On the other hand, 11 can only be divided by 1 and 11, satisfying the condition of being a prime number. Therefore, 11 is the next prime number that comes after 7.
