Answer Notes
A bipolar junction transistor (BJT) is constructed with three distinct semiconductor layers, which correspond to its three terminals: the collector, the emitter, and the base. In a standard circuit, the base serves as the control input that regulates the much larger current flowing between the collector and the emitter.
The distractors in this question list terminals that belong to a completely different type of transistor known as a Field Effect Transistor (FET). A FET utilizes a gate, source, and drain rather than a base, collector, and emitter.
