Correct answer: B. waxes
- A. cholesterol
- B. waxes
- C. chitin
- D. all of these
Explanation
Waxes are lipids that form water-resistant protective coatings on the surfaces of leaves and fruits, reducing water loss and blocking pathogens. Cholesterol is a membrane lipid mainly found in animals, while chitin is a structural polysaccharide, so choosing either confuses their functions with those of waxes.
