Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Equivalent weight $=$ Molecular weight/ valency factor
So, $N a C l, N a O H, K C l$ and $K B r$ all are ionic and they have valency factor equal to one.
Therefore, all will have their equivalent weight equal to their molecular weight.
