A

The output signal is amplified linearly.

B

The output signal is distorted and reaches a maximum level.

C

The output signal becomes zero.

D

The op-amp stops functioning.

Understanding the Answer

Let's break down why this is correct

When the input pushes the op‑amp beyond its power‑supply limits, the circuit can no longer produce a larger voltage. Other options are incorrect because A common mistake is to think the amplifier keeps multiplying the signal even when the input is too large; Some people think the output drops to zero when the input is too high.

Definition

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.
