Question

Which is the smallest whole number?

• A. $3$
• B. $1$
• C. $2$

Answer 1

The correct option is D

$0$

Whole numbers include all the natural numbers, i.e., $1,2,3,4,5$...., along with zero ($0$).
$1$ is the smallest natural number known, and $0$ is less than $1$.
Thus, the smallest whole number is $0$.
