Solution

The correct option is C Reason is correct but Assertion is incorrect
Presence of ${N H}_{4} C l$ suppresses the dissociation of ${N H}_{4} O H$ , hence concentration of ${O H}^{-}$ is reduced to minimum.
So addition of ${N H}_{4} O H$ to an aqueous solution of $B a {C l}_{2}$ in the presence of ${N H}_{4} C l$ (excess) does not precipitate $B a {(O H)}_{2}$ .
Furthermore, $B a {(O H)}_{2}$ is insoluble in water.
