It's D. Line Conditioner. "Power line conditioners are your best defense against voltage fluctuations, including brownouts, surges and line noise."

Selected Answer: D
Should be D here, a surge protector would be the cheapest to protect against a power SURGE or SPIKE, but for a fluctuation (up and down voltages), a Line conditioner would likely be more cost effective. From Cheryl Schmidt "Line Conditioners An alternative for computer protection is a line conditioner. Line conditioners, sometimes known as power conditioners, are more expensive than surge protectors, but they protect a computer from overvoltages, undervoltages, and adverse noise conditions over electrical lines. A line conditioner monitors AC electricity. If the voltage is too low, the line conditioner boosts voltage to the proper range. If the voltage level is too high, the line conditioner clamps down the voltage and sends the proper amount to the computer."
