A. Mix the blood in a salty solution to cause the RBCs to lyse.
B. Mix the blood in an isotonic solution and allow the WBCs to float to the top.
C. Mix the blood in a hypotonic solution, which will cause the RBCs to lyse.
D. Mix the blood in a hypertonic solution, which will cause the RBCs to lyse.
