(D) In diborane $(B_2H_6)$:$1.$ Each boron atom is $sp^3$ hybridized,which is correct.$2.$ The $H-B-H$ bridge angle is not $180^o$; it is approximately $97^o$,so statement $2$ is incorrect.$3.$ Each boron atom is bonded to two terminal hydrogen atoms via two terminal $B-H$ bonds,which is correct.$4.$ Diborane has $12$ valence electrons $(2 	imes 3 + 6 	imes 1 = 12)$,forming $6$ covalent bonds (each with $2$ electrons),so there are $12$ bonding electrons available,which is correct.Therefore,statements $1, 3,$ and $4$ are correct.

Column-$1$ (Reaction)	Column-$2$ (Main product)
$A$. $B_2H_6 + 2CO \longrightarrow$	$I$. $B_2O_3$
$B$. $B_2H_6 + 3O_2 \longrightarrow$	$II$. $2BH_3 \cdot CO$
$C$. $B_2H_6 + 6H_2O \longrightarrow$	$III$. $2H_3BO_3$

Select the correct statements for diborane $(B_2H_6)$:
$1.$ Boron is approximately $sp^3$ hybridized.
$2.$ The $H-B-H$ bridge angle is $180^o$.
$3.$ There are two terminal $B-H$ bonds for each boron atom.
$4.$ There are only $12$ bonding electrons available.
