Solution The correct option is D Light emitting diode (LED) bulbs
Incandescent electric bulbs are often used as lighting sources but they also give away more heat. This is not desirable as it results in the wastage of electricity. The fluorescent tube-lights and compact fluorescent lamps (CFLs) are efficient lighting sources than incandescent bulbs. Nowadays, the use of light emitting diode (LED) bulbs is increasing. For producing a given intensity of light, LED bulbs consume less energy as compared to other types of bulbs.
