Which code represents the ( Prefix ) Negative AC energy?

Explanation:
In this coding system, energy-related prefixes are built to quickly convey both the type of energy and its polarity. For Negative AC energy, the convention uses N to signal negative and x to represent alternating current, so the combination Nx clearly encodes Negative AC energy. This makes it the best choice because it directly matches both the polarity and the AC energy category in one compact code. The other sequences don’t pair the negative indication with the AC symbol in this scheme, so they don’t convey Negative AC energy as intended. Knowing this helps technicians identify hazards at a glance and apply the proper safety precautions.
