Question

State whether the following statement is true or false.

All odd numbers are prime numbers.

• A. True
• B. False

Answer 1

The correct option is B False

• Odd numbers: A number that is not divisible by $2$ is called an odd number.i.e. $1,3,5,......$
• Prime number: A number that has only two factors, $1$ and the number itself.

Not all odd numbers are prime numbers. For example $9,15,21$have more than two factors.
