Answer
Water vapour.
Explanation
## Step 1:The term "combustion" refers to the process of burning. In chemistry, it is a process wherein a substance reacts with an oxidizing element, typically oxygen. This reaction releases heat and light. ## Step 2:A hydrocarbon is a compound made from carbon and hydrogen. The combustion of hydrocarbons involves these molecules reacting with acts of combustion, leading to new product formation. ## Step 3:For complete combustion, sufficient amounts of oxygen should be present. If oxygen supply is ample, every atom of carbon in the hydrocarbon turns into a carbon dioxide molecule (CO2). Simultaneously, every two atoms of hydrogen in the hydrocarbon will turn into a water molecule (H2O). Therefore, the prevalent products of the complete combustion of hydrocarbons should be carbon dioxide and water. But in the given options, water is provided in the form of water vapour, which is still water but in its gaseous phase.
