Reaction that takes place at graphite anode in dry cell is
(a) \( \mathrm{Zn}^{2+}+2 \mathrm{e}^{-} \longrightarrow \mathrm{Zn}(\mathrm{s}) \)
(b) \( \mathrm{Zn}(\mathrm{s}) \longrightarrow \mathrm{Zn}^{2+}+2 \mathrm{e}^{-} \)
(c) \( \mathrm{Mn}^{2+}+2 \mathrm{e}^{-} \longrightarrow \mathrm{Mn}(\mathrm{s}) \)
(d) \( \mathrm{Mn}(\mathrm{s}) \longrightarrow \mathrm{Mn}^{+}+\mathrm{e}^{-}+1.5 \mathrm{~V} \)
