Solution

The correct option is C in the ground
A lightning conductor is a device used to protect buildings from the damaging effect of lightning.

Lightning conductor consists of a metallic rod, taller than the building, which is installed in the walls of the building during its construction. One end of the rod is kept out in the air and the other lower end is buried deep in the ground.

Hence, if lightning hits the building, it will strike the rod and be conducted to ground through wire.
