Single Replacement

Answer: Combustion is the correct answer.

Explanation:

When a substance combines with oxygen and energy is emitted in the form of heat and light, this process is called combustion.

There are two types of combustion.

1) Complete Combustion : It is a type of combustion in which fuel is quickly react with high amount of oxygen forming carbondioxide, water, heat and light.

2) Incomplete combustion : It is a type of combustion in which fuel is react with low amount of oxygen forming carbonmonoxide, carbon and water.
