Which of the following statement is correct?

Differential pressure deficit (DPD) is the reduction in diffusion pressure of the solvent in a system over its pure state. It has a positive value. DPD = OP - TP. Water is absorbed by a system having higher DPD from another system with lower DPD. It controls the entry of water into the cell by determining whether a cell will lose or gain water from an external solution or adjacent cells. Hence, the correct option is A.
