The answer is B. Unsaturated hydrocarbons will be hydrocarbons that have twofold or triple covalent securities between neighboring carbon particles. Those with no less than one carbon-to-carbon twofold bond are called alkenes and those with no less than one carbon-to-carbon triple bond are called alkynes.
