A

The output signal mirrors the input without distortion

B

The output signal is clipped, causing distortion

C

The output remains at zero volts

D

The output signal oscillates indefinitely

Understanding the Answer

Let's break down why this is correct

When the input is too large for the amplifier, the output can no longer rise or fall and is forced to the nearest supply voltage. Other options are incorrect because Some think the amp will keep mirroring the input forever, but the device has limits; The belief that the output stays at zero is wrong because the amp still drives toward the rail voltage.

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.
