Q. Hybridisation of the underline atom changes in
A) $\underline{A}lH_{3}\$changes to$\ AlH_{4}^{-}$
B) $H_{2}\underline{O}\$changes to$\ H_{3}O^{+}$
C) $\underline{N}H_{3}\$changes to$\ {NH}_{4}^{+}$
D) In all cases
Explanation

In $AlH_{3},\ Al$ is $sp^{2}$hybridised while in $AlH_{4}^{-}$, Al is $sp^{3}$ hybridised.
