Which of the following statements is incorrect regarding dry (Leclanche) cell?
(a) Cathode used in the cell is coated by powdered manganese dioxide and carbon.
(b) Most common application of this cell is in our transistors and clocks.
(c) At cathode, Mn is oxidised from \( +3 \) to \( +4 \).
(d) At anode \( \mathrm{Zn} \) is oxidised from 0 to \( +2 \).
