Answer & Explanation
The correct answer is Option A: A) To control the spread of flammable liquids.
A flame arrester is a device fitted to tank vents or pipes carrying flammable vapors. Its primary purpose is to prevent the propagation of a flame through a flammable gas mixture by rapidly cooling the flame below its ignition temperature, thus stopping flashback or explosion.
