Answer: Option (A) is the correct answer.
Explanation:
When a compound or substance reacts in the presence of oxygen and results in the formation of carbon dioxide and water along with the release of heat are known as combustion reaction.
For example, is a combustion reaction.
Heat is released in a combustion reaction because these are exothermic in nature.
Therefore, we can conclude that the following is an example of combustion type of reaction.
CH3OH + O2 → CO2 + 2H2O + heat

There are three carbon and 8 hydrogen present in propane molecule. The Lewis structure of propane is shown as:
Three molecules of such carbon atoms bound to eight molecules with hydrogen atoms make up the organic complex propane molecule.
It is known that carbon has 4 valence electrons and hydrogen has one valence electron. Carbon needs 4 extra electrons to complete its octet hence, it will share its electrons with with 4 hydrogen atom and complete its octet.
Carbon will be formed 4 bond . Three bond with hydrogen and one bond with carbon atom.
