Solution

The correct option is A Nichrome
Electric cooker, heater and iron, all contain a coil made of Nichrome. This coil acts like the filament of an electric bulb and gets heated up when electricity passes through it. When these appliances are switched on, the coil turns red hot and gives out the heat.
