C Correct answer
Explanation

Different instruments produce different wave shapes even when playing the same note at the same loudness. This difference in wave form is what we perceive as tone quality or timbre - it's why a flute and a violin sound different playing the same pitch. The wave shape determines the unique sound signature of each instrument.
