A

The output remains linear and proportional to the input.

B

The output voltage stabilizes at the supply voltage limit.

C

The op-amp enters a feedback loop.

D

The op-amp will self-destruct.

Understanding the Answer

Let's break down why this is correct

When the input tries to push the output higher than the power supply can provide, the op‑amp can no longer raise its voltage. Other options are incorrect because It is wrong to think the output would still follow the input linearly; Many people assume a saturated op‑amp suddenly starts a new feedback loop.

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.
