उत्तर
The turgor pressure is the pressure that allows the cell to maintain the shape of the cell. When there is endosmosis, there is the entry of water into the cell. This increases 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.
