Which of the following statements is true concerning the Halon 1301 fire extinguishing agent?

Correct Answer: Option D — Halon extinguishes the fire by a chain breaking reaction.

Halon 1301 acts as a fire extinguishing agent by interrupting the combustion chain reaction. Unlike water or CO2, which primarily cool or smother, Halon molecules interfere with the chemical free radicals in the flame zone, effectively stopping the fire at the molecular level without leaving residue.
