How can this reaction be made to proceed in the forward direction?

What is the correct order of melting points for the elements of group $13$?

Which of the following statements is/are correct for group $13$ elements?
$A$. $Al$ reacts with dil. $HCl$ to liberate $H_2$ gas
$B$. $Al$ reacts with conc. $HNO_3$ to liberate $H_2$ gas
$C$. Boron reacts with only acids to liberate $H_2$ gas
$D$. Anhydrous $AlCl_3$ reacts with moisture to liberate $H_2$ gas

In the reaction $B(OH)_{3} + 2 H_{2}O \rightarrow [B(OH)_{4}]^{-} + H_{3}O^{+}$,$B(OH)_{3}$ functions as:
