  1. The RBC will be unchanged since the saline solution is isotonic to the RBC
  2. The RBC will shrink as water is removed since the saline solution is hypertonic to the RBC
  3. The RBC will swell up as water enters the cell since the saline solution is hypotonic to the RBC
  4. The RBC will die since this saline solution is toxic to the cell
