Solution

The correct option is C Assertion is correct but Reason is incorrect
$A l {O H}_{3}$ is amphoteric in nature because it can react with both acid and bases.
Reaction of $A l {O H}_{3}$ in acidic solution:
$H C l (a q) + A l {O H}_{3} (a q) \to {A l C l}_{3} (a q) + 3 H_{2} O (l)$
Reaction of $A l {O H}_{3}$ in basic solution:
$A l {O H}_{3} + {O H}^{-} \to A l {(O H)}_{4}^{-}$
Al-O and O-H bond cannot be broken with equal ease in $A l {O H}_{3}$ .
So assertion is correct but reason is incorrect.
