What does PCB stand for?

Explanation:
PCB stands for Polychlorinated biphenyls. The term describes a family of related compounds: “polychlorinated” means many chlorine atoms attached, and “biphenyl” is the two-ring aromatic structure. The common usage treats PCB as a plural class, so the standard form includes an “s” at the end. The singular form isn’t the usual way this group is referred to, and the other options use incorrect spelling or grammar (such as omitting the final “s,” or forming “biphenylos”).
