Understanding the Answer
Let's break down why this is correct
The op‑amp first measures its own output and compares it with the input. Other options are incorrect because It assumes the error signal can exist before the amplifier knows the difference; It places the feedback before the amplifier learns there is a mistake.

Definition
Negative feedback in op-amps involves connecting the output back to the input to achieve self-correction. In negative feedback, the ideal op-amp forces the inverting and non-inverting inputs to be equal, maintaining stability and precise control.
