• A. Protein synthesis
• B. Waste storage and disposal
• C. Photosynthesis
• D. Cellular respiration

Correct answer: B

Rationale: Vacuoles in plant cells are primarily used for storage of water, nutrients, and waste products. In animal cells, vacuoles are smaller and serve various functions, including waste storage and disposal. Option B, 'Waste storage and disposal,' is the correct answer because vacuoles in animal cells help maintain cellular homeostasis by storing and breaking down waste materials. This process aids in detoxification and maintaining proper cellular function in animal cells, similar to the role of vacuoles in plant cells.
