Hypertonic
B
Hypotonic
✓
Isotonic
D
Dilute

Answer
Correct option: C.
Isotonic
Hypertonic means that the environment outside of the cell has a higher concentration of solutes than the cell itself.
A hypotonic solution is one in which the concentration of solutes is greater inside the cell than outside of it.
Isotonic means two solutions having the same concentration which means there are an equal number of solute molecules and an equal number of solvent molecules.
A liquid with a less solute concentration is called a dilute solution.
