The correct answer is:
E. copper rod
A dry cell consists of the following components:
Carbon rod (A) – Acts as the positive electrode (cathode).
Paste of manganese dioxide (B) – Acts as a depolarizer to prevent hydrogen buildup.
Paste of ammonium chloride (C) – Serves as the electrolyte.
Zinc case (D) – Acts as the negative electrode (anode) and also as the container for the cell.
A copper rod is not a part of a dry cell, making option E the correct choice.
