The correct answer is C. Heating effect.
A fuse is a safety device that is used to protect electrical circuits from damage caused by excessive current. When an excessive current flows through a fuse, the fuse wire melts and breaks the circuit, preventing damage to the circuit. The heating effect of electric current is the principle on which fuses operate.
The photoelectric effect is the emission of electrons from a metal surface when light is shone on it. The electrostatic effect is the attraction or repulsion of two objects due to their electric charge. The magnetic effect is the force that is exerted on a moving charge by a magnetic field.
