Solution

The correct option is A Turgor pressure exceeds wall pressure.
The turgor pressure is the pressure which allows the cell to maintain the shape of the cell. When there is endosmosis, there is entry of water in the cell. This increases the turgor pressure. The wall pressure is always equal to the turgor pressure. When the turgor pressure will exceed beyond the wall pressure, the cell wall will burst.
Thus, the correct answer is option B.
