What is the next prime number after 7?

• A. 8
• B. 10
• C. 11
• D. 13

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. To identify the next prime number after 7, we look at the integers following 7: 8, 9, 10, and 11. - The number 8 is divisible by 1, 2, 4, and 8, making it a composite number. - The number 9 is divisible by 1, 3, and 9, which also makes it a composite number. - The number 10 is divisible by 1, 2, 5, and 10, meaning it is also not prime. When we reach 11, we find that it is only divisible by 1 and 11, confirming that it is a prime number. Hence, 11 is indeed the next prime number after 7.
