The correct answer is B) It does not need oxygen for combustion. According to the Chemical Data Guide for Bulk Shipment, ethylene oxide exhibits the fire and explosion hazard of not needing oxygen for combustion. This means that ethylene oxide can burn and explode even in the absence of air or oxygen. The other answer choices are incorrect - ethylene oxide does not break down into toxic bromides, it does not react with water to produce flammable vapors, and its flash point is not 80.4°F. The fact that ethylene oxide can combust without oxygen is the key fire and explosion hazard associated with this chemical.
