In which solution might a cell maintain homeostasis through diffusion? A) isotonic B) hypertonic C) hypotonic D) concentrated

The correct option is A.

A solution is described as an isotonic solution when two solutions which are separated by a semi permeable membrane has the same osmotic pressure across the membrane. In an isotonic solution, molecules can easily move across the semi permeable membrane from one solution to the other without any change in the solute concentration of the solutions.
