In everyday life, a "theory" means a hunch, or a figure. In science a theory is the demonstrated consequence of a few trials. i.e. nuclear theory... we realize that molecules exist and that everything is made of iotas, yet in science the expression "law" is not utilized as a part of the case that ensuing confirmation ever surfaced to make a superior or more exact theory.
Answer:
Water potential 
Explanation:
As we know,
Water potential is equal to the sum of pressure potential and solute potential
Ψ
ΨS
ΨP
Where Ψ is the water potential
ΨS is the solute potential
ΨP is the pressure potential
Given -
Solute potential ( ΨS ) 
Pressure potential ( ΨP ) 
Substituting the given values, we get -
Ψ

Ψ

I think that it might be B. It also might be D
