D) low input impedance and high distortion.

Question

Quizplus · Accepted Answer

The emitter-follower amplifier has a high input impedance because the input is applied to the base terminal, which has a high input impedance. It also has a low distortion because the output voltage follows the input voltage, but with a lower amplitude. However, the input impedance is not as high as that of a common-collector amplifier, and the gain is less than unity.
