Correct option b) A saturated fatty acid
When only one double bond in the molecules that is also known as monounsaturated fat. If there is more than one double bond that is known as polyunsaturated fat.
Unsaturated fatty acids have one or more than one carbon- carbon band double bonds. That indicates the maximum possible numbers of hydrogen atoms are bonds to each carbon in the molecule. These carbon form double bonds with the carbons next to them.
Alkenes contain carbon- carbon double bonds and unsaturated hydrocarbons with the molecular formula is Cn H2n. This is made of chains where some carbon atoms are not fully saturated with hydrogen atoms.
