Solution

The correct option is B
The movement of water occurs from a high water potential to a lower water potential.
$\begin{matrix} Cell & Water Potential (osmotic potential + pressure potential) A & - 1 + 0.5 = - 0.5 B & - 0.6 + 0.3 = - 0.3 C & - 1.2 + 0.6 = - 0.6 D & - 0.8 + 0.4 = - 0.4 \end{matrix}$
