The biconcave shape of the blood cells helps in the flow of the blood easily and these cells have no nucleus like other cells to have high amount of hemoglobin that is a pigment that carry oxygen and other gases for easy gaseous exchange.
Due to their flexible biconcave shape they can bend and flex accordingly during entering capillaries. The shape of the RBC helps in making stacks and large surface to area ratio.
Thus, the correct answer is - option C.
