Awater solution that has the same salt concentration as the cells is said to be hypotonic isotonic

The correct answer would be isotonic.

Isotonic solutions are the set of solutions which have the same concentrations of solutes.

They have same osmotic pressure across a semipermeable membrane.

The net movement of water is zero in such solutions.

Hence, the water solution that has the same salt concentration as the cells is  said to be the isotonic solution.
