Answer: Option (a) is the correct answer.
Explanation:
When a fat contains high proportion of fatty acid molecules which have no double bonds then it is known as a saturated fat.
For example, animal fats are mostly saturated.
Fats which are solid at room temperature are known as solid fats. Butter, beef fat etc are all solid at room temperature. Most of the animal food gives solid fats.
Thus, we can conclude that saturated fat is most likely a solid at room temperature.
