Which is a correct match of the below?

The correct chemical formula for butane is C4H10. Butane is a colorless, flammable gas commonly used as a fuel. It's part of the alkane series, where each member has a molecular formula following the pattern CnH2n+2. For example, methane (CH4) is the simplest alkane, followed by ethane (C2H6), propane (C3H8), and then butane (C4H10). Other options like methane and ethane listed have incorrect formulas listed, with methane being CH4, ethane C2H6, and pentane C5H12.
