The correct answer is: A.When placed in a solution containing a high salt concentration.

Here's why:

High salt concentration: When a cell is placed in a solution with a high salt concentration (hypertonic solution), the concentration of solutes outside the cell is higher than inside the cell. This causes water to move out of the cell (osmosis) in an attempt to balance the solute concentrations. As a result, the cell loses water and shrinks.

Explanation of the other options:

B.Isotonic solution: In an isotonic solution, the concentration of solutes outside the cell is equal to the concentration inside the cell. Water moves in and out of the cell at an equal rate, so the cell size remains ...
