$A$ healthy individual has $A$ grams of haemoglobin in every $B$ mL of blood. These molecules play a significant role in the transport of $C$ gases.
Choose the correct option for $A$, $B$, and $C$.

Oxyhaemoglobin can transport

What is the chloride shift responsible for transporting?

Approximately $70\%$ of carbon dioxide absorbed by the blood is transported to the lungs:

$A$: Major part of carbon dioxide is transported in the form of sodium bicarbonate.
$R$: $0.3 \; ml$ of carbon dioxide is transported per $100 \; ml$ of blood in dissolved state in plasma of blood.
