Answer: A) Osmotic pressure
Step-by-step explanation:
Soluble contributed to the movement of water between the cells and the surrounding medium by the osmotic pressure. As, the hydrostatic pressure is defined as when the force that exerted by the fluid in opposition to the wall and cause its movement between the sections.
And the brownian movement are the irregulation movement of small particle that are suspended in liquid. The haphazard motion of the molecules and the atoms are known as random motion. Therefore, the osmotic pressure is the correct option.
