Question

The sum of two prime numbers is

• A. Prime
• B. Odd
• C. Sometimes even and sometimes odd
• D. Even

Answer 1

The correct option is C

Sometimes even and sometimes odd

Explanation for correct option:

Option C: Sometimes even and sometimes odd

Prime Numbers:The numbers which have only two factors $1$ and the number itself are called Prime Numbers.

Lets take few prime numbers, and add them

$$\begin{gathered} \text{3 + 5 = 8(even)} \\ \text{5 + 2 = 7 (odd)} \\ \text{7 + 11 = 18(even)} \end{gathered}$$

Hence, the sum of two prime numbers is both an even and odd number.

Hence, option C is the correct answer.
