Read the following statements and select the correct option.
Assertion (A) : Phosphorus is stored in Kerosene.
Reasoning (R) : Phosphorus catches fire if exposed to air.

Correct option is C

The correct answer is (c) (A) is false but (R) is true.
Assertion (A) is false. Phosphorus is actually stored under water, not in kerosene. This is because phosphorus is highly reactive and can spontaneously ignite in air. Storing it under water prevents it from coming into contact with air and reacting.
Reasoning (R) is true. Phosphorus does indeed catch fire if exposed to air. This is because phosphorus is a highly reactive nonmetal. When it comes into contact with oxygen in the air, it reacts to form phosphorus pentoxide, which is a white powder. This reaction is exothermic, which means that it releases heat. The heat released from the reaction can be enough to ignite the phosphorus, causing it to catch fire.
