Unlike CO₂ or N₂O, O₂ Cannot Be Stored as a Liquid

Unlike CO₂ or N₂O, O₂ cannot be stored as a liquid at room temperature but must be kept in special cryogenic containers. Why is this so?

A) O₂ is 20 times less diffusible than CO₂, N₂O, or cyclopropane.
B) O₂ has a critical temperature well below room temperature.
C) O₂ has an extremely high gas solubility coefficient.
D) O₂ has a boiling point below well below room temperature.
