An LED, widely used in modern lighting and electronic displays, stands for which of the following?

Explanation

LED stands for Light Emitting Diode, a small electronic component that produces light efficiently when an electric current passes through it, converting a large proportion of the electrical energy directly into visible light rather than wasting much of it as heat. Compared to older incandescent bulbs, LEDs are significantly more energy efficient and typically last far longer before needing replacement. LEDs are now widely used in general household lighting, electronic device displays, and traffic signals, among countless other applications.
