Which statement best describes why packed red blood cells are usually transfused instead of whole blood?

B) Whole blood is diluted with plasma so the recipient might not receive the needed number of red blood cells.
C) Whole blood contains antibodies that could attack the recipient's antigens on their red blood cells.
D) Whole blood contains plasma proteins that could cause edema in the patient.
