A
RBCs to plasma
B
plasma to RBCs
C
lungs to blood
D
blood to lungs

Solution

(B) The correct answer is $B$.
During the transport of carbon dioxide,bicarbonate ions $(HCO_3^-)$ are produced inside the red blood cells $(RBCs)$ and diffuse out into the plasma.
To maintain the electrical neutrality (ionic balance) of the $RBCs$,chloride ions $(Cl^-)$ move from the plasma into the $RBCs$.
This process is known as the chloride shift or the Hamburger phenomenon.
