The correct answer is - a hypotonic solution as it can pass the cell wall and cell membrane into the cell.

When a plant cell is in freshwater it takes up the water with the help of osmosis and begins to swell but the cell wall does not let it burst and become turgid.

Thus, the correct answer is - a hypotonic solution as it can pass the cell wall and cell membrane into the cell.
