During CO2 transport, HCO3 diffuses from erythrocytes to plasma and in turn upsets the ionic balance momentarily. In order to keep the ionic balance, an equal number of Cl− pass into the erythrocytes from plasma. The process is known as

Solution
The correct option is C Hamburger phenomenon
About 70% of CO2 is converted to bicarbonate ions
(HCO−3) and transported in plasma. CO2 diffuses into
RBCs, combines with-water and forms carbonic acid {H2CO3).
H2CO3 being unstable quickly dissociates Into H+ and
HCO−3. HCO−3 ions are quite diffusible. Therefore,
HCO−3 diffuses from RBCs into the plasma. To maintain the
ionic balance CI− ions move from the plasma into the RBCs. This
exchange is called chloride shift or Hamburger's phenomenon.So, the correct answer is 'Hamburger phenomenon'.
