D

Answer Notes
In solid-state electronics, bipolar junction transistors (BJTs) and field-effect transistors (FETs) have analogous components. The BJT features a base, emitter, and collector, while the FET features a gate, source, and drain.
The collector in a BJT is the terminal where the primary output current flows out of (or into) the device, depending on the type. This functions identically to the drain in a FET, which serves as the primary output terminal for the channel's current.
Other options are incorrect because the base corresponds to the gate (both are control terminals), and the emitter corresponds to the source (both act as the origin of the charge carriers).
