Show answer and explanation

Correct answer: (a) frequency of the sitar string with the frequency of other musical instruments

Explanation

Adjusting the tension and plucking of a sitar string changes its frequency (pitch) of vibration.

This tunes the string's frequency to match the frequency of other musical instruments in the orchestra.

Amplitude and intensity relate to loudness, not pitch matching, so they are distractors.
