The correct answer is: A.It will swell and burst.

When a red blood cell is placed in distilled water, the water is hypotonic relative to the inside of the cell (meaning the solute concentration is much lower in the distilled water than in the cell). Water will move into the cell by osmosis, causing the cell to swell. Because the cell membrane is not rigid enough to withstand the pressure of too much water entering, the cell will eventually burst, a process known as hemolysis.
