Answer:
Isotonic solution.
Step-by-step explanation:
Isotonic solution may be defined as the solution that has same concentration as present in the cells. The net movement of water molecules does not change the concentration of the solutes in solution on either site.
The water solution has same salt concentration as in the cells means that the concentration of solutes ( salt) in solution is equal to concentration of solutes present inside the cells. So, the movement of water molecules from inside or outside of the cell would be equal.
Hence, the solution is isotonic solution.
