The correct option is C Imbibition pressure
When the imbibant is kept in a confined area, pressure increases with an increase in the imbibant volume. This pressure is known as imbibition pressure. It is also known as the matric potential since it develops due to the matric potential of the imbibing substance.
Osmotic pressure can be defined as the minimum pressure that must be applied to a solution to halt the flow of solvent molecules through a semipermeable membrane (osmosis).
A transpiration pull could be simply defined as a biological process in which the force of pulling is produced inside the xylem tissue. This force helps in the upward movement of water into the xylem vessels. In this process, loss of water in the form of vapours through leaves are observed.
Root pressure is a force or the hydrostatic pressure generated in the roots that help in driving the fluids and other ions from the soil in upwards directions into the plant's vascular tissue – Xylem. This process is produced by osmotic pressure in the cells of the root.
The correct answer is "Imbibition pressure"
