The correct answer is **c. Feedback**.
When the microphone is placed close to and facing the speaker, it can pick up the sound produced by the speaker. If the audio signal from the microphone is amplified and sent back to the speaker, it can create a loop where the sound continuously re-amplifies, leading to a loud, high-pitched squeal known as feedback.
