Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
A reactant that is entirely consumed when a reaction goes to completion is known as limiting reactant.

The amount of reactant limits the amount of product formed.

For example, consider the reaction: $C + O_{2} \to C O_{2}$

If $1$ mole of $C$ and $2$ moles of oxygen are present, then $C$ is the limiting reagent and oxygen is the excess reagent.

The amount of product formed is $1$ mole and not $2$ moles.

Hence, both assertion and reason are correct and reason is the correct explanation for assertion.
