What is the next prime number after 7?

• A. 8
• B. 9
• C. 10
• D. 11

Answer: (D)

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. After 7, the sequence of natural numbers continues with 8, 9, and 10, all of which can be divided by numbers other than 1 and themselves. Specifically, 8 can be divided by 1, 2, 4, and 8; 9 can be divided by 1, 3, and 9; and 10 can be divided by 1, 2, 5, and 10. In contrast, 11 can only be divided by 1 and 11, confirming it as a prime number. Thus, following 7, the next number that meets the criteria of a prime number is indeed 11.
