Which of the following is a basic logic gate?

• A. Adder
• B. Transistor
• C. And gate
• D. Capacitor

Answer: (C)

Basic logic gates are the building blocks of digital electronics, performing simple Boolean operations on binary signals. An And gate implements the logical conjunction: its output is high only when both inputs are high. This simple rule is foundational for controlling when actions occur in a circuit, since it requires multiple conditions to be true before something happens. For example, if both inputs are 1, the output is 1; otherwise, it’s 0. Adder, transistor, and capacitor don’t perform the basic Boolean function that defines a logic gate: an adder computes a numeric sum, a transistor is a switching device used to build circuits (not a gate by itself), and a capacitor stores charge. Therefore, the And gate is the correct basic logic gate in this context.
