Explanation:

A potentiometer, as a variable - resistance sensor, has three terminals. One terminal is for the input voltage (connected to one end of the resistive element), one terminal is for the output voltage (connected to the wiper which moves along the resistive element), and one terminal is connected to the other end of the resistive element. So the correct option is D.
