Solution

The correct option is D Aluminium
Lightning rods are made of conducting materials to give a path for the charges from the lightning to pass through and reach the ground. In this case, Copper and aluminium being conductors, are suitable for the construction of a lightning rod. Insulators like wood and plastics would not allow charges to pass through them.
