Answer: Option (a) is the correct answer.
Explanation:
A saturated fatty acid is defined as an acid that contains chains of hydrogen and carbon atoms that are connected by single bonds.
For example, [tex]C_{6}H_{13}COOH[/tex] is a saturated fatty acid.
Whereas an unsaturated fatty acid contains double bond and linoleic acid is a poly-unsaturated acid, that is, there will be more that one double bonds.
Monounsaturated fatty acid contains one double bond.
Thus, we can conclude that a fatty acid completely filled by hydrogen with all carbons in the chain linked by single bonds is known as a saturated fatty acid.
