A

The output voltage will clip and remain at the maximum or minimum power supply level.

B

The op-amp will continue to amplify the input signal without any distortion.

C

The output will oscillate between the power supply limits.

D

The op-amp will cease to function entirely.

Understanding the Answer

Let's break down why this is correct

When the input pushes the op‑amp beyond its supply rails, the amplifier can no longer follow the signal. Other options are incorrect because Some think an op‑amp will keep amplifying no matter what; Oscillation sounds like a ping‑pong of the output.

Op-amps have output limitations due to the voltage range of their power supply. When the output voltage exceeds this range, the op-amp saturates and outputs the maximum or minimum voltage. Saturation can lead to signal clipping near the power supply rails.
