The correct answer is C. Methane.
Methane is the simplest alkane, with the chemical formula CH4. It is a colorless, odorless, and flammable gas that is the main component of natural gas. Methane is also produced by the decomposition of organic matter, such as plants and animals, and is a major source of greenhouse gas emissions.
Propane is a hydrocarbon with the chemical formula C3H8. It is a colorless, odorless, and flammable gas that is used as a fuel for heating, cooking, and transportation. Propane is also used in the production of plastics and other chemicals.
Butane is a hydrocarbon with the chemical formula C4H10. It is a colorless, odorless, and flammable gas that is used as a fuel for heating, cooking, and transportation. Butane is also used in the production of plastics and other chemicals.
Decane is a hydrocarbon with the chemical formula C10H22. It is a colorless, odorless, and flammable liquid that is
used as a fuel and solvent. Decane is also used in the production of plastics and other chemicals.Methane is the simplest alkane because it has the fewest carbon atoms. It is also the most abundant alkane in nature.
