A
Always equal to solute potential
B
Equal to pressure potential minus solute potential
C
Always equal to osmotic potential
D
A tendency of a solution to take up water from another solution across a membrane

Solution:

Water potential ( $ψ_{w}$ ) is a concept fundamental to understanding water movement. Solute potential ( $ψ_{s}$ ) and pressure potential ( $ψ_{p}$ ) are the two main components that determine water potential.
$ψ_{w}$ = $ψ_{s}$ + $ψ_{p}$ .
