(a) Bromine is released at the cathode
(b) Lead is deposited at the anode
(c) Bromine ions gain electrons
(d) Lead is deposited at the cathode

Solution

(d) Lead is deposited at the cathode.

Reaction at the cathode:
Lead ions gain two electrons from the cathode and reduce to lead metal at the cathode.

${Pb}^{2 +} + 2 e^{-} \overset{Reduction}{\to} Pb (Lead metal)$
