A

bandwidth

B

gain

C

input impedance

D

offset voltage

Understanding the Answer

Let's break down why this is correct

The output follows the rule Vout = (V+ - V-) × Gain. Other options are incorrect because Bandwidth tells how wide a range of frequencies the op-amp can handle, not how much the input difference is multiplied; Input impedance is how much current the op‑amp draws from the source, it does not scale the output.
