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

Explanation:
Bond order is inversely proportional to the bond length.
In molecule. one nitrogen is double bonded to nitrogen and one oxygen is single bonded to nitrogen and hydrogen bond.
- Bond order between the (N=O) bond is 2 which means that bond length between the (N=O) bond is shorter than that of the N-O bond.
- Bond order between the (N-O) bond is 1 which means that bond length of the N-O bond is longer than that of the bond length of (N=O) bond.
