Water moves out of the cell.
B
Water does not move at all.

Verified step by step guidance1
Understand the concept of an isotonic solution: An isotonic solution has the same concentration of solutes as the inside of the cell, meaning there is no net movement of water across the cell membrane.
Recognize the principle of osmosis: Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
Apply the concept of equilibrium: In an isotonic solution, the concentration of solutes is equal inside and outside the cell, so water moves equally in both directions to maintain equilibrium.
Consider the dynamic nature of water movement: Even though there is no net movement, water molecules are constantly moving in and out of the cell at equal rates.
Conclude that in an isotonic solution, water moves equally in and out of the cell, maintaining balance without changing the cell's volume.
