A

The output remains in the linear region only when the input voltage is below the threshold.

B

Output saturation occurs only when the input voltage exceeds the supply voltage.

C

The output voltage can continue to increase even after reaching the supply limits, indicating non-linear behavior.

D

The output is always equal to the input voltage in the linear region.

Understanding the Answer

Let's break down why this is correct

When the output reaches the supply limits, the op‑amp is saturated. Other options are incorrect because The idea that only a small input keeps the output linear is wrong; Thinking that the input must exceed the supply voltage is mistaken.

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.
