Adetect and amplify the voltage difference between the inputs at pins 1 and 2

Bdetect and amplify the voltage difference between the inputs at pins 1 and 5

Cdetect and amplify the voltage difference between the inputs at pins 2 and 3

Ddetect and amplify the voltage difference between the inputs at pins 3 and 5

AI Explanation

The correct answer is C) detect and amplify the voltage difference between the inputs at pins 2 and 3. The purpose of the differential amplifier segment in a 741 operational amplifier is to detect and amplify the voltage difference between the two input pins, which are pins 2 and 3. This differential amplifier configuration allows the op-amp to amplify the difference between the two input signals, which is a key function of operational amplifiers. The other answer choices are incorrect because they do not correctly identify the input pins that the differential amplifier is designed to monitor and amplify the voltage difference between.
