The correct option is A If both assertion and reason are CORRECT and reason is the CORRECT explanation of the assertion.
When HCl in a jar is poured into a jar containing burning candle, Very slowly dribble the hydrochloric acid into the jar happens so carbon dioxide gas is produced quietly and steadily and $C O_{2}$ does not support combustion i.e. does not allow substances to burn in it .
Thus, HCl is act as a fire extinguisher.
Thus, Option A is correct.
