(A, B, C, D ARE ALL CORRECT (NOTE: THE PROVIDED OPTIONS DO NOT CONTAIN THE CORRECT COMBINATION A, B, C, D; HOWEVER, BASED ON THE QUESTION, ALL STATEMENTS ARE FACTUALLY CORRECT.)) In a lead storage battery,the anode is made of lead $(Pb)$ and the cathode is a grid of lead packed with lead dioxide $(PbO_2)$.$A$ $\sim 38\%$ solution of sulphuric acid $(H_2SO_4)$ is used as the electrolyte.During the charging process,the discharge reactions are reversed:$1$. At the anode: $PbSO_{4(s)} + 2e^- \rightarrow Pb_{(s)} + SO_{4(aq)}^{2-}$$2$. At the cathode: $PbSO_{4(s)} + 2H_2O_{(l)} \rightarrow PbO_{2(s)} + SO_{4(aq)}^{2-} + 4H_{(aq)}^+ + 2e^-$Thus,statements $A$,$B$,$C$,and $D$ are all correct.
