Select the correct homologous class of alkane.

Correct option is A

The correct homologous class of alkanes is: (a) CH₄, C₂H₆, C₃H₈, C₄H₁₀

• Alkanes belong to a homologous series, which means they follow a general formula and have similar chemical properties.
• The general formula for alkanes is CnH₂n+2.
• CH₄ (methane), C₂H₆ (ethane), C₃H₈ (propane), and C₄H₁₀ (butane) all follow this pattern.
• The other options, while including alkenes or other hydrocarbons, do not form a homologous series of alkanes.
