Correct Answer: Harmonics present
Solution : The correct option is Harmonics present.
The harmonics present determine the quality of a musical note. Overtones or higher frequencies that exist in addition to the basic frequency of a sound are referred to as harmonics. The timbre or quality of the sound is determined by the quantity and relative intensity of the harmonics. A lot of variables can influence the harmonics contained in a sound, including the form and size of the instrument, the materials used to construct the instrument, and how the instrument is played.
