The Vital Capacity is the maximum volume of air that can be exhaled after taking the deepest breath possible.
Breath is the inhalation or exhalation of air for maintaining the gaseous exchange. Inhalation is taking the air (for oxygen) inside the lungs. Whereas exhalation is the removal of air (of carbon dioxide) outside the lungs.
Vital Capacity can also be denoted as VC. Mathematically, it is equal to the sum of Inspiratory Reserve Volume, Tidal Volume, and Expiratory Reserve Volume. The volume of VC is approximately 4800 mL. However, the amount can vary according to the age and health of a person.

The correct answer will be option-A
Explanation:
The centrifugation of the blood shows that 45% of the blood is composed of the cellular content and 55% blood plasma or liquid.
Erythrocytes or red blood cell constitute for about 41% of the total blood cells which transports the oxygen by binding it to the haemoglobin. The presence of haemoglobin is the reason the cell appears red which cause the color of the blood to appear red.
The remainder of the cell is white blood cells or leukocytes which play important role in providing the defence mechanism against the pathogen.
Thus, option-A is the correct answer.
