The right answer is C) Make sure electrical hazards are resolved immediately.
The different electrical risks are:
Risk of direct contact with an electrified part
Risk of indirect contact with a conductive part accidentally switched on
Risk of "remote" electrification (without contact), by priming
Risks of fire and exposure, due in particular to arcing during a short circuit, and the accumulation of static electricity causing sparks.
