C is the correct answer. During combustion, a hydrocarbon (2C2H2) and oxygen (5O2) make carbon dioxide (4CO2) and water vapour (2H2O). Hydrogen is therefore oxidised to water.

the equation for the reaction is as follows

2CH₂ + 5O₂ ---> 4CO₂ + 2H₂O

this a combustion reaction

Combustion is when a hydrocarbon compounds burns in the presence of oxygen and yields carbon dioxide and water vapour as products.

In the given equation, C₂H₂ is a hydrocarbon and its reacting with oxygen to yield CO₂ and H₂O

these hydrocarbons act as fuels because combustion reactions give out a large amount of energy.

Therefore the answer is C. combustion
