Question

Let’s help Daphne select the prime number out of the given even numbers. Which of the following numbers is a prime number?

• A. $22$
• B. $22$
• C. $34$
• D. $2$

Answer 1

The correct option is D $2$

The only prime number among the given even numbers is $2$.

• All other even numbers can be divided by $2$, so they will have at least three factors—$1,2$, and the number itself.

Hence, $2$ is the only even prime number.
