Solution

The correct option is D Carbonic anhydrase
Most of the carbon dioxide molecules are carried as part of the bicarbonate buffer system. Carbon dioxide enters the red blood cells in the tissue capillaries. The carbon dioxide molecule combines with water to form carbonic acid. This reaction is catalysed by the enzyme carbonic anhydrase, which is found in the red blood cells. Carbonic acid then dissociates to form bicarbonate ions and hydrogen ions.
Thus, the correct answer is option D.
