Answer
(a) Note from a musical instrument is shown by figure (d) because the sound produced by the musical instruments comprises of different frequencies and amplitudes resulting in a mixed type of wave form.
(b) Soft note is shown by figure (a) because this wave has low amplitude.
(c) Shrill note is shown by figure (c) because this wave has high frequency.
