Correct Option: D

In chemistry, a homologous series is a series of compounds with a similar general formula, possessing similar chemical properties due to the presence of the same functional group. C₆H₁₄ stands for Hexane which is an alkane with six carbon atoms. In the alkane homologous series, each member differs from the previous one by a CH₂ group (or 14 atomic mass units). The CH₂ group is called Methylene Group. So the higher homologue of Hexane is Heptane (C7H16).
