Red blood cells are placed into a solution of unknown solute concentration. after an hour they have all burst open. the best explanation is that the solution 1. had a very high concentration of solutes. 2. was at equilibrium. 3. had a very high concentration of solvent had no solutes.

Option C

Explanation:

Red blood cells when places in a solution having higher concentration of solutes then the cells bursts.

The red blood cells when kept in the such of a solution bursts because of the hypotonic solution outside the cell.

The cells when kept inside hypotonic solution the solution will move from outside to inside of the cell and the cell will burst.
