Answer:
C)Call an electrician to repair or replace the switch.
Explanation:
When a house is designed, the electrical system is also designed with the same care. However, in many cases the power grid is outdated, either because the construction is old, or by adding equipment that was not programmed, undersizing this network.
Because of this, electrical wiring and even switches can be faulty and allow electrical current to escape and shock people in the home. This is very dangerous and when it happens an electrician should be called immediately to repair or replace faulty switches.
