D Correct answer
Explanation

Quality, or timbre, allows a listener to distinguish between two sounds that have the same pitch and loudness. It is determined by the specific combination and relative intensities of the overtones or harmonics present in the sound wave. This is why a piano and a violin sound different even when playing the same note.
