Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The expression for the equivalent mass of the element is, $Equivalent mass of the element = \frac{Atomic mass of the element}{Valency}$
Thus, the equivalent mass of an element is variable. It depends on the valency of the element. Higher is the valency of the element lower will be its equivalent mass.
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
