Solution
The correct option is A Fuse
Fuse is the primary protection device against short circuits. It ensures current limiting effect under short-circuit conditions. Whenever the current in the circuit exceeds its limiting value, the fuse wire gets heated up, melts and breaks the circuit. Hence it protects the entire circuit from damage.
