Answer 1

Option D is correct.

Step-by-step explanation

We are told that two musical notes that are a fourth apart, the frequency of the lower note is (3/4) of the frequency of the higher note.

If the frequency of the higher note is f,

Frequency of the lower note = (3/4) × (Frequency of the higher note)

= (3/4) × f

= (3/4)f
