For combustion reaction to take place there should beoxygenflamefuelall of the abov

The correct answer is "all of the above". For a combustion reaction to occur, you need three things: oxygen, fuel, and heat (which is often provided by a flame).

Here's a step-by-step explanation:

1. Fuel: This is the substance that will react with oxygen to produce heat and light. It can be a solid, liquid, or gas. Examples include wood, gasoline, and natural gas.

2. Oxygen: This is the substance that the fuel reacts with, also known as the oxidizer. In most cases, the oxygen comes from the air around us.

3. Heat (Flame): Combustion reactions are exothermic, meaning they produce heat. However, they also require a certain amount of heat to get started. This is known as the ignition temperature. A flame can provide this initial heat.

So, in summary, for a combustion reaction to take place, you need fuel to burn, oxygen to react with the fuel, and heat to start and continue the reaction.
