Correct option is C
Electrical fires are caused by faulty electrical systems, improper wiring, and excessive current flow, leading to overheating and fire hazards. Among the given options:
· Overloading of wires occurs when too many appliances are connected to a circuit, drawing more current than the wires can handle, leading to overheating and fire risks.
· Loose connections create high resistance at joints, generating sparks and excessive heat, which can ignite surrounding materials.
· Electric short circuits happen when live and neutral wires come into direct contact, causing a sudden surge of current that can lead to fire and equipment damage.
· Open doors do not contribute to electrical fires. While open doors may affect ventilation, they do not directly cause an electrical fire.
