D Correct answer
Explanation

All three power line issues can damage computers. Line sag (undervoltage) can cause system instability and data corruption, line surge (overvoltage/spikes) can fry components, and line noise (EMI/RFI) introduces signal errors that corrupt data transfer. Power protection devices like UPS and surge protectors mitigate these problems.
