What are the names of the electrodes of a bipolar junction transistor?

A bipolar junction transistor (BJT) is a three-terminal semiconductor device widely used for switching or amplifying electronic signals. The three electrodes (or terminals) are specifically named the emitter, the base, and the collector. The base acts as the control point; a very small current entering the base controls a much larger current flowing between the emitter and the collector. The incorrect options consist of generic functional terms (like input, output, supply) rather than the actual physical names of a BJT's electrodes. Keep in mind that a different transistor type, the Field Effect Transistor (FET), uses the terms gate, drain, and source.
