Solution

The correct option is A 1
Reactions occurring in basic solution should not contain free $H^{+}$ ions in the final balanced equation.
Since the medium is basic, the free $H^{+}$ ions will combine with $O H^{-}$ ions to form neutral water molecule.
$H^{+} + O H^{-} ⇌ H_{2} O$
Hence, for the reaction in basic medium, $O H^{-}$ ions (equal to the number of $H^{+}$ ions) are added on both sides of the equation. The $H^{+}$ ions and $O H^{-}$ ions appearing on the same side of the reaction are combined to give water molecules.
