Detailed Solution

concept - A dry cell is one type of electric battery that is generally used for home and portable electronic devices. A battery is a device that consists of one or more electrochemical cells that convert chemical energy into electrical energy.
A dry cell consists of a metal container in which a graphite rod or metal electrode is covered with a low-moisture electrolyte paste. Generally, the metal vessel will be zinc, with the base acting as the negative electrode (anode) and the carbon path acting as the positive electrode (cathode). It is surrounded by manganese dioxide and a low-moisture electrolyte such as ammonium chloride paste, which produce a maximum of 1.5 V and are not reversible.
So, Zinc acts as a negative electrode.
Hence, the correct option is (1).
