Solution
The correct option is C Isotonic
Two solutions having the same osmotic pressure at a given temperature are called isotonic solutions.
The solutions with more osmotic pressure are called hypertonic solutions. Those with lower value of osmotic pressure are hypotonic solutions.
If a cell is placed in a hypotonic solution, the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane, there will be a net flow of water into the cell and the cell will gain volume.
When a cell is placed in a hypertonic solution, the solute concentration outside the cell is higher than inside the cell. In this case water is lost from the cell and the cell shrinks.
