Solution
The correct option is C Zinc
A zinc-carbon battery is a dry cell battery between a zinc metal electrode and a carbon rod from an electrochemical reaction between zinc and manganese dioxide mediated by a suitable electrolyte.It is usually conveniently packaged in a zinc can which also serves as the anode with a negative potential, while the inert carbon rod is the positive cathode.
Zinc acts as a negative electrode as it has more negative potential and acts as the anode.
