The correct answer is: D.water moving into the root cells of a plant.

This is an example of osmosis because osmosis refers specifically to the movement of water molecules across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration.

In the case of plant roots, water moves from the soil (where the water concentration is higher) into the root cells (where the water concentration is lower), typically through the cell membrane, which is semipermeable. This is a classic example of osmosis.
