• A. Statement I is corect; Statement II is correct; Statement II is the corect explanation of Statement I.
• B. Statement I is correct; Statement II is correct;Statement II is not the correct explanation of Statement I.
• C. Statement I is correct; Statement II is incorrect.
• D. Statement I is incorrect; Statement II is true.

Answer 1

The correct option is A Statement I is corect; Statement II is correct; Statement II is the corect explanation of Statement I.

$Al(OH{)}_3$ is amphoteric

$\underset{Base}{Al(OH{)}_3}+3HCl\to AlC{l}_3+3H_{2}O$
$\underset{Acid}{Al(OH{)}_3}+NaOH\to Na\left[Al\right(OH{)}_4]$

High charge and small size of $A{l}^{3+}$ makes $Al-O$ and $O-H$ bonds equally ionisable.
