When storing pure phosphorus to prevent it from reacting, an element that doesn't readily react with phosphorus needs to be used. Among the options provided, Argon (Ar) is the most suitable choice. Argon is an inert gas that is non-reactive with phosphorus and can be used to create an oxygen-free environment, preventing the phosphorus from coming into contact with oxygen and bursting into flame.
