The correct answer identifies linoleic acid (an omega-6 fatty acid) and alpha-linolenic acid (an omega-3 fatty acid) as essential unsaturated fatty acids in the human diet. Essential fatty acids are those that the body cannot synthesize on its own and must be obtained through food.

Linoleic acid serves many functions in the body, including playing a crucial role in cell membrane structure and function, as well as supporting various physiological processes like inflammation and blood clotting. Similarly, alpha-linolenic acid is important for cardiovascular health and has anti-inflammatory properties. These fatty acids contribute to overall health and productivity.

The other options do not provide the correct combinations of essential fatty acids nor accurately classify their omega designations. It's essential to understand that omega-3 and omega-6 are specific families of essential fatty acids that provide various health benefits, and misidentifying them can lead to confusion regarding their sources and functions in the diet.
