Which of the following is a lipid?

Explanation:
Lipid-like substances are fats and oils that do not mix with water and are mainly used for long-term energy storage and making cell membranes. Oil fits this description because it is composed mostly of triglycerides, a classic type of lipid. Rice is a carbohydrate (starch), which provides quick energy and is water-soluble in the sense of dissolving in water. Meat contains proteins and fats but isn’t itself a lipid category. Vitamin B is a water-soluble vitamin, not a lipid. So oil is the lipid.
