Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
It could be the movement of water (osmosis), or other (diffusion). If a cell is placed in an isotonic solution, that means the amount of stuff inside the cell and outside the cell is equal.There will be some movement of water and salt across the cell membrane, but there will be no net concentration change.
