• B. an odd number
• C. either even or odd
• D. prime number

Answer 1

The correct option is B

an odd number

A odd number is the number which is not the multiple of $2$, or we can say that it is expressed as $2m+1$,

Example: $1,3,5,7,13$etc, we noticed that these numbers are not divisible by $2$.

Let's take two odd numbers $a=3$ and $b=5$;

So,

$$\begin{gathered} a\times b \\ =3\times 5 \\ =15 \end{gathered}$$

We, can see that $15$ is odd.

So, the product of two odd number is a odd number.
