Answer: A

Explanation:

Voltage fluctuation is a systematic variation of the voltage waveform or a series of random voltage changes of small dimensions that occur over a period of time. Voltage fluctuation can be caused by a variety of factors, such as changes in demand, changes in the power system, faults on the power system, or the switching of large loads.
