Oxygen tanks can explode if the gas if ignited because oxygen is __________________.

• A. Flammable
• B. Inert
• C. Nonflammable
• D. Explosive

Answer: (A)

Oxygen dramatically enhances combustion and can drive a rapid, violent burn when ignition occurs in a confined, high‑pressure system. It isn’t a fuel itself, but it is an oxidizer that makes fires burn much more vigorously. In a pressurized oxygen tank, a spark or flame can cause materials inside and around the tank to ignite quickly, releasing a lot of energy in a short time and potentially leading to an explosion. That safety-oriented phrasing describes oxygen as flammable in this context because it highlights how readily fires can start and escalate in oxygen‑rich environments. The other choices don’t fit because inert and nonflammable imply no burning or supporting of combustion, and explosive would suggest detonation without an initiating flame, which isn’t the usual behavior of oxygen gas alone.
