Answer:
D. The cell membrane has been ruptured
Explanation:
The word lysis comes from the Greek word 'lusis" which means loosening. When used to described cells, it means the cells have burst or ruptured. Therefore, D is correct.
The cell ruptures when it is placed in a hypotonic solution, that is, a solution that has a lower solute concentration (and therefore a higher water concentration) than inside the cell. Water enters the cell by osmosis, eventually leading to the cell bursting.
