Answer:

The correct option is <em>D. They will shrink.</em>

Explanation:

An isotonic solution can be described as a solution in which the number of solutes is the same among two solutions or barriers. As a result, no concentration gradient is developed in the two cells and hence, no exchange of solutes occurs in between them.

If the solutes are increased in the solution, then the amount of solutes will be more outside the cell as compared to the inside of the cell. As a result, a concentration gradient will develop which will lead to moving out the solvent from the cells. Hence, the cells will shrink.
