The balloon filled with water most likely represents a vacuole, which is a membrane-bound organelle that stores water and other materials in plant cells. 
The plastic bag that contains water represents the plant cell's cell membrane, which surrounds and protects the cell and regulates what substances can enter and leave. 
The plastic box represents the cell wall, which provides structural support and protection for the plant cell. Choice B is the only option that correctly matches these structures with their functions in a plant cell.
