The correct answer is: B. Isotonic
An isotonic solution is a solution that has the same concentration of solutes as another solution. When a cell is placed in an isotonic solution, there is no net movement of water into or out of the cell. This is because the concentration of water is the same on both sides of the cell membrane.
A hypertonic solution is a solution that has a higher concentration of solutes than another solution. When a cell is placed in a hypertonic solution, water will move out of the cell into the solution. This is because the concentration of water is higher outside the cell than inside the cell. The cell will shrink as water moves out.
A hypotonic solution is a solution that has a lower concentration of solutes than another solution. When a cell is placed in a hypotonic solution, water will move into the cell from the solution. This is because the concentration of water is higher inside the cell than outside the cell. The cell will swell as water moves in.
I hope this helps!
