Water potential is the sum of opposing forces of
Osmotic pressure and diffusion pressure
Solute potential and osmotic potential
Solute potential and pressure potential
Diffusion pressure deficit and turgur pressure
Solute Potential/ Osmotic Potential (Ψs) -
The amount by which water potential is reduced as a result of the presence of solute.
- wherein
It is always negative.
Hence option c is correct.
