Answer: b. hemolysis
Step-by-step explanation:
A hypotonic solution is the one where the solute concentration is less than that of the RBCs. Therefore, the solvent will enter inside the RBCs due to osmotic pressure. This will lead to the increase in concentration of the solvent inside the cells this will lead to the swallowing of the cell and with generation of the high internal pressure inside the cell the cell will burst. This will result in hemolysis.
