The ending or suffix of the hydrocarbon name tells the bonds found between carbon atoms in the molecule. Therefore, option (B) is correct.
Hydrocarbons are entirely made up of only two kinds of atoms which are carbon and hydrogen. Hydrocarbons are typically colorless gases and weak odors. Hydrocarbons can be relatively complex structures and can be classified into four subcategories, alkanes, alkenes, alkynes, and aromatic hydrocarbons.
Hydrocarbons such as propane and butane are used for commercial fuel purposes in the form of LPG and the molecular formula for the compounds is CxHy.
In the nomenclature of hydrocarbons, the suffix of the name indicates what type of bond is present between the atoms. If all carbon atoms have a single covalent bonds then the suffix is "ane". If one or more carbon-carbon double bonds are present then the suffix is "ene". If the triple bond is present then the suffix in the name of the hydrocarbon is "yne".
