Detailed Solution

When a voltage is supplied to it, it emits light, which implies it turns electrical energy into light energy.

The Light Emitting Diode (LED) can only function in forwarding bias circumstances.

When a Light Emitting Diode (LED) is biassed forward, free electrons from the n-side and holes from the p-side are pushed towards the junction.

When forward biassed, light-emitting diodes emit either visible light or invisible infrared light.

Remote controllers employ LEDs that generate invisible infrared light.

LEDs that emit red, yellow, orange, green, and blue light are commercially available.

Option 2, i.e. diode, is the right answer.

LED is an abbreviation for Light Emitting Diode.
