The correct answer is option 4: Gun powder.

Gun powder is a mixture of potassium nitrate, powdered charcoal, and sulfur. It is commonly used as a propellant in firearms and fireworks. Each component in the mixture plays a specific role.

Potassium nitrate, also known as saltpeter, is an oxidizing agent that provides oxygen for the combustion reaction. It is responsible for the rapid release of energy when gun powder is ignited.

Charcoal, in a powdered form, serves as the fuel in the mixture. When heated, it undergoes combustion, producing carbon dioxide and releasing heat and gas.

Sulfur acts as a stabilizer, ensuring that the gun powder mixture remains in a solid form and does not explode prematurely.

The combination of these three ingredients creates a highly combustible mixture that is widely used in various industries.
