Final Answer:
Linoleic acid and linolenic acid, are considered essential fatty acids.
thus correct option is C. linoleic acid and linolenic acid
Step-by-step explanation:
Essential fatty acids are crucial components that the human body cannot synthesize on its own and must be obtained through the diet. Linoleic acid and linolenic acid, both present in option C, are considered essential fatty acids.
Linoleic acid belongs to the omega-6 fatty acid group, while linolenic acid belongs to the omega-3 fatty acid group. These fatty acids play vital roles in various physiological functions, including maintaining cell structure, supporting the immune system, and contributing to the synthesis of important signaling molecules.
Option A includes lecithin, which is a phospholipid and not an essential fatty acid, and linoleic acid, which is correct. Options B and D contain compounds like cholesterol, triglycerides, stearic acid, and butyric acid, none of which are classified as essential fatty acids. Cholesterol, for instance, is a sterol, and while triglycerides contain fatty acids, they are not classified as essential.
thus correct option is C. linoleic acid and linolenic acid
