Solution

The correct option is C TP
Osmotic pressure (OP) is also defined as the pressure required to completely stop the entry of water into a solution through a semi-permeable membrane. Turgor pressure (TP) is the hydrostatic pressure that develops due to the entry of water in a cell or a system. Wall pressure (WP) is the pressure exerted by the cell wall over the protoplast to counter the turgor pressure. Suction pressure (SP) is given by:
SP = OP - TP.
Hence, the answer is TP.
