A B-II fire extinguisher has a minimum capacity of __________.

Correct Answer: Option C — 10 pounds of dry chemical

Fire extinguisher ratings under 46 CFR classify a B-II unit as containing a minimum of 15 pounds of carbon dioxide, 1.5 gallons of foam, 10 pounds of dry chemical, or 10 pounds of dry powder. Therefore, 10 pounds of dry chemical satisfies the B-II capacity requirement.
