In a conventional zinc–carbon dry cell, the outer container acting as the anode is made of which metal?

Explanation

In a conventional zinc–carbon dry cell, the zinc container is the anode and is oxidised as the cell discharges. The electrolyte is a paste containing salts such as ammonium chloride and zinc chloride. Manganese dioxide is reduced in the cathode mixture; the central carbon rod serves as a current collector rather than the consumed cathode reactant.
