Answer 1

True statements: 1, 2, and 3.

- 2 is true: fats are a primary fuel during rest and low-intensity activity.
- 3 is true: fat‑soluble vitamins (A, D, E, K) dissolve in lipids (dietary triglycerides) and require fat for absorption.
- 4 is false: fats are more energy‑dense than carbohydrates (≈9 vs ≈4 kcal/g).
