Which prefix denotes positive AC energy?

Explanation:
The key idea is how prefixes encode polarity for AC energy in this labeling scheme. The B prefix indicates AC energy, and the trailing character conveys polarity. The symbol x is used to denote positive polarity, so Bx directly signals positive AC energy. The other forms—Bns, Bx24, and B24—either indicate a different polarity (or state) or add a qualifier (like a voltage level) without specifying positive polarity. That makes Bx the best fit for denoting positive AC energy.
