Answer: Option B) Lipids generally don't dissolve in water.
Explanation:
All lipids are small biomolecules that are insoluble in water but dissolve readily in nonpolar organic solvents, and contain fatty acids, sterols. So, not all lipids are made of fatty acids and glycerol, and the chemical properties of each lipids depends on their composition.
Thus, all lipids share the characteristics of not dissolving in water.
