What is a Corona?
Direct Answer
Option A: Corona is a diffuse discharge from a single sharp conductor that slowly releases some of the available energy. Generally, corona on its own is incapable of igniting a gas.
Corona is a discharge caused by ionization of air near sharp conductors; however, in standard tanker operations, a corona discharge alone does not possess sufficient energy to ignite a hydrocarbon gas-air mixture.
