A

Inverting amplifier

B

Non-inverting amplifier

C

Voltage follower

D

Comparator

Understanding the Answer

Let's break down why this is correct

The non‑inverting amplifier gives a fixed gain that does not depend on the input signal level. Other options are incorrect because The inverting amplifier has a lower input impedance, so it can load the source and shift the phase; A voltage follower provides unity gain; it does not amplify signals.
