Final answer:
Fat in the body primarily serves to protect organs and supply energy, offering significant caloric content and aiding in the absorption of lipid-soluble vitamins (Options A and B).
Step-by-step explanation:
The two major roles of fat in the body are to protect organs and supply energy. Fat acts like a cushion, protecting internal organs from damage and insulating the body to maintain proper temperature.
Additionally, fats are important for absorbing lipid-soluble vitamins such as vitamins A, D, E, and K, and serve as a significant energy reserve, providing about 9 calories per gram.
This is over double the energy provided per gram of carbohydrates or protein, both of which offer only about 4 calories per gram.
While fats are essential for various bodily functions, including as a structural component for hormones and signaling molecules, it is important to consume them in moderation to maintain health.
Hence, the correct answers are Options A and B.
