A Correct answer
Explanation

As a cell becomes more turgid (takes in water), it pushes against the cell wall, and the wall pushes back with equal force (wall pressure). These pressures increase together until they balance the osmotic potential. This follows the physical principle that as internal pressure increases, the containing wall's opposing pressure must also increase.
