B Correct answer
Explanation

Graphite, an allotrope of carbon, is an excellent conductor of electricity due to its delocalized electrons in the layered structure. This makes it unique among non-metals. Bromine, Iodine, and Oxygen are typical non-metals that are insulators (poor conductors). Graphite's conductivity explains its use in electrodes and motor brushes.
