The correct option is C protect building from the damaging effects of lightning
The answer is option C.
As a storm cloud approaches, there is a conductive pathway established between the statically charged cloud and the lightning rod. The static charges gradually migrate along this pathway to the ground, thus reducing the likelihood of a sudden and explosive discharge.
Lightning conductors provide a low-resistance path to ground that can be used to conduct the enormous electrical currents when lightning strikes occur. If lightning strikes, the system attempts to carry the harmful electrical current away from the structure and safely to the ground. The system has the ability to handle the enormous electrical current associated with the strike.
