If the concentrations of sodium chloride in the interstitial fluid surrounding cells decreases and the concentration of other solutes remains constant

a - the cells will shrink

b - the cells will swell

c - the fluid outside of the cells will become isotonic

d - the cells will not change

e - the fluid outside of the cells will become hypertonic

A - the cells will shrink

The correct answer will be option-B.

Explanation:

The cells respond differently when placed in different solutions like isotonic, hypertonic and hypotonic solutions.

In the given question, the sodium chloride concentration in the fluid decreases thereby making the solution hypotonic with low solute concentration and high water potential.

This force the movement of water from the hypotonic solution to the inside of the cell as the osmotic movement takes place from high solvent concentration to low concentration, therefore, cell will swell.

Thus, Option-B is the correct answer.
