• B. $RBC$
• C. $WBC$
• D. platelets

Answer 1

Answer: (B)

Carbonic anhydrase is an enzyme present in red blood cells that catalyses the reaction between carbon dioxide and water to form carbonic acid, which subsequently dissociates into $H^{+}$ and $HC{O}_3^{-}$ ions. This reaction is one of the fastest known biological reactions and controls the elimination of carbon dioxide from the body.
