A Correct answer
Explanation

The fuse wire must be placed in the live wire so that when it melts due to excess current, it disconnects the power supply from the appliance completely. If the fuse were in the neutral wire, the appliance would remain connected to live voltage even when the fuse blows, creating a serious shock hazard. The earth wire is for safety grounding and never carries current during normal operation. Placing the fuse in the neutral wire defeats the entire safety purpose of the fuse.
