Match List-$I$ with List-$II$. Choose the correct answer from the options given below:

List-$I$	List-$II$
$A$. Melting point $[K]$	$I$. $Tl > In > Ga > Al > B$
$B$. Ionic Radius $[M^{+3} / pm]$	$II$. $B > Tl > Al \approx Ga > In$
$C$. $\Delta_{i} H_1 [kJ \ mol^{-1}]$	$III$. $Tl > In > Al > Ga > B$
$D$. Atomic Radius $[pm]$	$IV$. $B > Al > Tl > In > Ga$

In the reactions $I$ and $II$,the covalencies of $Be$ and $Al$ in $X$ and $Y$ are respectively:
$I$ $Be(OH)_2 + NaOH \text{ (excess)} \rightarrow X$
$II$ $Al(OH)_3 + NaOH \text{ (excess)} \rightarrow Y$

Which of the following properties does not support the anomalous behavior of $Boron$?

Aluminum dissolves in mineral acids and aqueous alkalis and thus shows amphoteric character. $A$ piece of aluminum foil is treated with dilute hydrochloric acid or dilute sodium hydroxide solution in a test tube and on bringing a burning match stick near the mouth of the test tube,a pop sound indicates the evolution of hydrogen gas. The same activity when performed with concentrated nitric acid,the reaction does not proceed. Explain the reason.

Which one of the following metallic oxides exhibits amphoteric nature?

Inorganic graphite is
