Quizplus · Accepted Answer

The correct choice is A because if there is a signal present at the input to the pre-amplifier but no output detected, the issue lies within the pre-amplifier itself. Moving the left bracket to the input of the pre-amplifier helps isolate and confirm the fault is indeed in the pre-amplifier.
