If the concentration of solutes in a cell is less than the concentration of solutes in the surrounding fluid, then the extracellular fluid is said to be

A) stable.
B) isotonic.
C) hypotonic.
D) hypertonic.
E) amphipathic.

Hypertonic

A solution that has a higher concentration of solutes compared to another solution, leading to potential osmotic movement of water out of a cell.

Extracellular Fluid

Fluid that exists outside the cells of an organism, including blood plasma, lymph, and interstitial fluid, providing a medium for transport of nutrients and waste.

Solute Concentration

The amount of a substance dissolved in a unit volume of solution, often referred to in terms of molarity, molality, or mass percent.
