Approximately seventy percent of carbon dioxide absorbed by the blood will be transported to the lungs

  • as bicarbonate ion

  • in the form of dissolved gas molecules

  • by binding to RBC

  • as carbamino - haemoglobin

Answer

A.

as bicarbonate ion

Because of its high solubility, about 7% of carbon  dioxide gets dissolved in the blood plasma and is carried to the wings in the same way. The largest fraction of carbon dioxide, i.e., (about 70% ) is converted  to bicarbonates (HCO3-) and transported in the plasma.
