Which of the following is an example of a digital logic gate?

A digital logic gate is a component in electronic circuits that performs a basic logical function on one or more binary inputs to produce a single binary output. The NAND gate is a fundamental building block of digital electronics and is classified as a digital logic gate. It operates based on the principle that the output is low (0) only when all of its inputs are high (1), and otherwise, the output is high (1). This characteristic makes the NAND gate capable of implementing various logical functions and is widely used in combinational and sequential logic circuits.

In contrast, the other choices—such as resistors, batteries, and inductors—are passive components used in analog circuits. They do not perform logical operations on binary inputs; instead, they are components that manage voltage, current, or energy in a circuit without the capability for logical decision-making. Thus, among the options provided, the NAND gate is the only example of a digital logic gate.
