Question

When there is a lower concentration of water outside of a plant cell rather than inside a plant cell, the plant will tend to

Answer 1

Poorly written question. The question wants to ask about tonicity and osmolarity. Despite many teachers treating them as the same thing, they are not. Osmolarity has to do with the osmotic pressures of water and is calculated using total solute amounts. Tonicity is only referring to the relative concentrations of solutes that cannot pass through a semipermeable membrane, which separates the two solutions. This means only water can move across the membrane and does so in a dynamic process (always moving and in all directions).

So, for your example: The outside of the cell has a higher solute concentration than the inside. Since the solute cannot pass the membrane only the water does. More water exits the cell than enters the cell and thus the cell shrivels (in things with cell wall the cell wall usually remains the same but the cell plasma membrane shrivels.
