Question

Multiplicative identity of whole number is given by

• A. $1$
• B. $0$
• C. Both $0\text{\hspace{0.17em}and\hspace{0.17em}}1$
• D. None

Answer 1

The correct option is A

$1$

The explanation for the correct option:

The multiplicative identity of the whole number is a property that states that if a number is multiplied by another number, such that the product is the first number itself, then the second number is called the multiplicative identity of the first number.

The product of any number with 1 is the number itself.

$a\times 1=a$, where $a$ is a whole number.

Thus, $1$ is the multiplicative identity of the whole number.

Hence, the correct option is (A)
