Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Oxidation is loss of electrons and we know oxidation occurs at anode and it is also true that in calcium hydride hydrogen is present as hydride. So, $H^{-}$ will loss electron and form $H_{2}$ gas at the anode.
