Explanation:

To determine the correct answer, we analyze the concept of sound phase and ear perception. When standing to the side (like right of) a sound source, the distance from the source to each ear differs, causing the sound waves to reach the ears out of phase. Standing behind, below, or in front of the source results in more symmetric distances to both ears, so the sound is more likely in phase. So option A fits.

Answer:

A. to the right of
