When a live conductor of public electric supply breaks down and touches the earth, a current will flow from the conductor to the earth. This is because the earth has a much lower resistance than the conductor, so the current will take the path of least resistance. The flow of current will cause the earth to become energized, and anyone who touches the earth will receive an electric shock.
Option B is incorrect because the supply voltage will not
