Solution

The correct option is C $p = B r_{2} q = a l c . K O H r = N a N H_{2} s = r e d h o t i r o n t u b e$
$C H_{2} = C H_{2} {B r}_{2} - - \to C H_{2} B r - C H_{2} B r Electrophilic addition reaction alc. KOH - ---- \to C H_{2} = C H B r Elimination reaction {N a N H}_{2} - ---- \to C H \equiv C H$

$\Rightarrow 3 C H \equiv C H red hot iron tube - --------- \to C_{6} H_{6} under the influence of a organometallic Nickel catalyst at 873K$

Hence option D is correct.
