White phosphorus is always kept under A. Benzene B. Kerosene C. Ether D. Water

White phosphorus is always kept under water. This is because white phosphorus is highly flammable and can spontaneously ignite when

exposed to air. Water helps to prevent this by creating a barrier between the phosphorus and the oxygen in the air.

Benzene, kerosene, and

ether are all flammable liquids that could ignite white phosphorus if they were in contact with it. Therefore, they are not suitable for storing white phosphorus.

Water is the only option that is safe to store white phosphorus in. It is non-flammable and does not react with phosphorus.
