How many prime numbers are there between 1 and 16?

• A. 4
• B. 6
• C. 8
• D. 10

Answer: (B)

To determine how many prime numbers exist between 1 and 16, we first need to understand what a prime number is. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

Now, let's identify the prime numbers within that range. The numbers we need to consider between 1 and 16 are:

2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16.

Out of these numbers, the prime numbers are:

• 2 (only divisible by 1 and 2)

• 3 (only divisible by 1 and 3)

• 5 (only divisible by 1 and 5)

• 7 (only divisible by 1 and 7)

• 11 (only divisible by 1 and 11)

• 13 (only divisible by 1 and 13)

Counting these gives us a total of 6 prime numbers (2, 3, 5, 7, 11, and 13) between 1 and 16. Therefore, the answer indicating that there
