Saturated fat, a fatty acid in which the hydrocarbon molecules have a hydrogen atom on every carbon and thus are fully hydrogenated. (By way of comparison, the hydrocarbon molecules of unsaturated fats have two carbons that share double or triple bonds and are therefore not completely saturated with hydrogen atoms.)
A saturated fat is defined as a fat that contains long chains of carbon and hydrogen atoms that contains only single bonds and atleast one carboxylic acid group.
For example, butyric acid, lauric acid etc are saturated fats.
Whereas fats that contain atleast double bond in their carbon and hydrogen chain are known as unsaturated fat.
Thus, we can conclude that out of the given options fat depicted in option (A) is a saturated fat.
