Explanation
Halon (A) and CO2 (C) are both approved suppression agents for electrical and computer fires because they extinguish flames without conducting electricity and leave no damaging residue - critical when protecting sensitive equipment.
Water (B) is wrong because it conducts electricity, creating electrocution hazards and causing additional equipment damage. Soda acid (D) is wrong for the same reasons - it's a liquid-based agent designed for Class A fires (ordinary combustibles) and is corrosive to electronics.
Memory tip: Think "no liquid, no residue" - for computer rooms, you need agents that are clean and non-conductive. Halon and CO2 are both gases that fit this rule; water and soda acid are both liquid-based and fail it immediately.
