The correct answer reflects the typical fatty acid composition found in margarine. Margarine is primarily made from vegetable oils, which are rich sources of polyunsaturated fatty acids (PUFA) and monounsaturated fatty acids (MUFA). The processing of these oils often results in a blend that retains significant amounts of PUFA and MUFA, followed by smaller amounts of saturated fatty acids (SFA). This composition makes margarine a more heart-healthy alternative compared to butter, which has a higher saturated fat content.

Margarine typically aims to provide healthier fats, which is why PUFA and MUFA are prioritized in its formulation. This understanding is essential for dietary planning and nutrition education, as it emphasizes the importance of selecting fats that support cardiovascular health.
