Which statement describes the movement of water when a cell swells and bursts due to osmosis?

A
Water went into the cell because the concentration of water inside the cell was lower than the concentration outside the cell.
B
Water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.
C
The cell membrane used energy to move water into the cell because there was not enough water inside the cell
D
The cell membrane used energy to move water out of the cell because there was too much water inside the cell
