Too much voltage for a short period of time is a spike.
Too much voltage for a long period of time is a surge.
Not enough voltage for a short period of time is a sag or dip Not enough voltage for a long period of time is brownout A short power interruption is a fault A long power interruption is a blackout You MUST know all of the power issues above for the purpose of the exam.

Sure, I'd be happy to provide a detailed explanation of each of the terms listed in the question.
A. Spike: A spike is a sudden, short-duration increase in voltage that lasts for a few milliseconds or less. Spikes are often caused by lightning strikes or the switching of large electrical loads, and can cause damage to electronic equipment if not properly protected.
B. Blackout: A blackout is a complete loss of power to an electrical grid or system, typically caused by a failure in the power generation or distribution infrastructure. Blackouts can last from a few minutes to several days, and can have serious consequences for public safety, health, and economic activity.
C. Surge: A surge is a temporary increase in voltage that lasts for a few seconds or less, typically caused by the sudden application or removal of a load from an electrical circuit. Surges can also be caused by lightning strikes, power outages, or other external factors. Like spikes, surges can cause damage to electronic equipment if not properly protected.
D. Fault: A fault is a defect or malfunction in an electrical circuit or system that can cause it to fail or operate improperly. Faults can be caused by a variety of factors, including design flaws, component failures, and environmental conditions. Faults can be detected and corrected through various diagnostic and repair techniques, depending on the nature and severity of the problem.
Based on the definitions above, the correct answer to the question is C. surge, which refers to a temporary increase in voltage that lasts for a few seconds or less.
