The best answer is A. The purpose of the cell wall is to hold the cell in a specific shape, usually rectangular or square. For example, a plant cell's wall keeps it rigid so that the plant can stand up.

If the cell does not have a wall, it can easily change shape to accommodate for things coming in and out of the cell.
