Which statement describes an alkene?

Explanation:
Alkenes are hydrocarbons that contain a carbon–carbon double bond. This C=C bond is the feature that makes them unsaturated and sets them apart from saturated hydrocarbons, which have only single bonds. The other statements describe saturated hydrocarbons or the alkane formula (CnH2n+2) and saying there are only single bonds, which isn’t true for alkenes. So, highlighting the carbon–carbon double bond best identifies an alkene.
