Solution
The correct option is D Light Emitting Diode
A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it
A P-N junction can convert absorbed light energy into electric current. Here the reverse happens that is the P-N junction emits light when electrical energy is applied to it. The charge carriers recombine in a forward-biased P-N junction as the electrons cross from the N-region and recombine with the holes existing in the P-region. Free electrons are in the conduction band of energy levels, while holes are in the valence energy band. A part of the energy gets dissipated in order to recombine the electrons and the holes and this energy is emitted in the form of heat and light.
