Final answer:
Linoleic and linolenic acids, which are essential fatty acids, must be consumed in the diet and are found in Omega-3 and Omega-6 fats.
Step-by-step explanation:
Essential fatty acids must be provided by the diet and include linoleic and linolenic acids, which are found in c) Omega-3 and Omega-6 fats. These essential fatty acids, specifically alpha-linolenic acid (an omega-3 fatty acid) and linoleic acid (an omega-6 fatty acid), are necessary for good health as they are not synthesized by the human body. They play a crucial role in growth and development, the synthesis of other unsaturated fatty acids like arachidonic acid, and the transport and metabolism of cholesterol. Foods rich in omega-3 fatty acids include oily fish, walnuts, and flax seeds, while omega-6 fatty acids are commonly found in cooking oils like corn oil and in processed foods.
