    D. periodic fluctuations in the frequency of sound waves

    Explanation:

    Beat is referred to the phenomena that occurs when to sound waves interfer with each other and they have different frequencies.

    This difference is what creates a beating, wich in sound waves manifest as high and low sounds, this as a result of the oscilating frequency.
