The correct option is A Plasma
Blood is made up of plasma and corpuscles. Plasma is the pale coloured extracellular fluid that holds the blood cells. 55% of the body's total blood volume is plasma. It contains mostly water (up to 95% by volume), and dissolved proteins, glucose, clotting factors, electrolytes, hormones and carbon dioxide and helps in transportation. Whereas platelets, RBC and WBC do not carry minerals, other food to the body cells. Thus, option A is correct.
