Solution

The correct options are
A
Lead will be reduced

C
Bromine will be oxidized

In the electrolysis of lead bromide ions present will be $P b^{2 +}$ and $B r^{-}$ .

At cathode: ${P b^{2 +}}_{(l)} + 2 e^{-} - > P b_{(l)}$

At anode: ${B r}^{-} - > B r_{(g)} + e^{-}$

$B r_{(g)} + B r_{(g)} - > {B r_{2}}_{(g)}$
