What is the boiling point of liquid oxygen?

Explanation:
Boiling point is the temperature at which a liquid changes to a gas at a given pressure, usually 1 atmosphere. For liquid oxygen, that transition happens at about -183°C, which is -297.3°F. So the temperature that marks the liquid-to-gas change at standard pressure is -297.3°F. Other options don’t fit because they are either warmer than the boiling point, meaning oxygen would already be a gas at 1 atm, or colder than that point, where oxygen would still be a liquid (or solid at even lower temperatures).
