• A. displacement reaction
• B. double displacement reaction
• C. oxidation reaction
• D. isomerisation reaction

Answer 1

Answer: (C)

oxidation reaction

Combustion of a fuel is the oxidation reaction, it includes a hydrocarbon and oxygen as the reactants and always produces carbon dioxide and water as products.
$C_x{H}_y+O_2\left(g\right)\to C{O}_2\left(g\right)+H_{2}O\left(g\right)$
Fuel combustion also known as burning fuel is the process by which a fuel is consumed in an exothermic chemical reaction that releases a great deal of heat and light.
