Solution

The correct option is B
turgor pressure exceeds wall pressure

Turgor pressure is the pressure of the cell contents on the cell wall while wall pressure is the pressure exerted by the cell wall on the cell contents. Healthy plant cells are turgid and plants rely on turgidity to maintain rigidity. If the turgor pressure is more than the wall pressure, then the cell ruptures and the contents burst out.
