b. 880 hz
c. 660 hz
d. 220 hz

Explanation:

Step1: Understand the concept of an octave

An octave means doubling the frequency.

Step2: Calculate the frequency

Given the base frequency \( f = 440\space Hz \). The frequency of a note an octave above is \( 2\times440\space Hz\).

$$2\times440 = 880\space Hz$$
