The question asks for the end products of the complete combustion of hydrocarbons. Complete combustion occurs when there is an ample supply of oxygen, leading to the full oxidation of carbon and hydrogen atoms present in the hydrocarbon.
Correct Option: A) CO₂ + H₂O — In complete combustion, hydrocarbons react with sufficient oxygen to produce carbon dioxide (\( \text{CO}_2 \)) and water (\( \text{H}_2\text{O} \)). This is the most efficient form of combustion, where all carbon is oxidized to \( \text{CO}_2 \) and all hydrogen to \( \text{H}_2\text{O} \).
