Select the correct answer. which component of the blood is part of the body’s immune system? a. plasma b. platelets c. red blood cells d. white blood cells

The correct answer is D, white blood cells.
We know that red blood cells deliver nutrients and are not apart of the immune system; platelets are responsible for coagulation, which has nothing to do with the immune system, and plasma is a substance that, again, has nothing to do with immunity. White blood cells are the only things that fight disease (antibodies are white blood cells)!
