Which two oxygen forms are specifically named in the material?

• A. Gaseous Oxygen and LOX
• B. Liquid Oxygen and Oxygen Gas
• C. Gaseous Oxygen and Medical Oxygen
• D. Gaseous Oxygen and Atmospheric Oxygen

Answer: (A)

Oxygen in safety materials is discussed in its practical forms, not just as a single substance. The material explicitly names two: gaseous oxygen and LOX. LOX is the standard abbreviation for liquid oxygen, a cryogenic liquid stored for use as an oxidizer. Gaseous oxygen is the oxygen you encounter as a gas at ambient conditions. The pairing of gaseous oxygen and LOX reflects the two forms you must consider for handling, storage, and hazards. Other terms like medical oxygen or atmospheric oxygen aren’t the forms highlighted in this context, and calling oxygen gas by a different label doesn’t add a distinct form beyond the gaseous state. So the two forms named are gaseous oxygen and LOX.
