Correct Answer

Explanation

A note is called an octave of another note when it has a frequency that is exactly double or half the frequency of the other note. This means that if one note is higher in pitch than another note, and the frequency of the higher note is exactly double the frequency of the lower note, they are said to be one octave apart. Similarly, if the frequency of the higher note is exactly half the frequency of the lower note, they are also considered to be one octave apart.
