Which code corresponds to the prefix for negative AC energy?

Explanation:
In this coding scheme, the two-letter prefix identifies the energy type and its polarity. Negative alternating current energy uses the CX prefix, which designates that specific combination within the system. The other options add digits or extra letters that signal different categories or qualifiers, so they don’t match the standard prefix for negative AC energy. Therefore, CX is the correct prefix.
