Solute concentration
is higher outside the
cell causes the cell
shrink.

If these are your answer choices -

A. Hypertonic solution

B. Isotonic solution

C. Hypotonic solution

D. Both A and C

then your answer is:

Correct option is - A

Hypertonic solution

A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell. Water crosses the cell membrane in both directions, but more water leaves the cell than enters it. Therefore, the cell will shrink due to exosmosis.
