b. 440 hz
c. 880 hz
d. 660 hz

Explanation:

Step1: Understand the concept of an octave

An octave above a frequency means doubling the frequency.

Step2: Calculate the frequency

Given the base frequency \( f = 440\ \text{Hz} \), the frequency one octave above is \( 2\times f\).

$$2\times440 = 880\ \text{Hz}$$
