Solution

The correct option is A Systole
  • A contractile vacuole is a sub-cellular organelle found in few protozoans.
  • It is a specialized vacuole which helps in regulating the quantity of water inside a cell.
  • It expands when water enters them and is called the diastole and it contracts or bursts when the water present in the vacuole along with wastes is expelled out of the cell and is called the systole.
  • So, the correct answer is 'Systole'.
