Solution

The correct option is D efflux of $H C O_{3}^{Θ}$ ions from RBC
Carbonic acid (H2CO3) dissociates into Hþ and HCO3 – ions; therefore, the concentration of both Hþ and HCO3 – is increased in the red blood cell. HCO3 – can diffuse out of the red blood cell into plasma whereas Hþ cannot. In order to maintain electrical neutrality, chloride ions diffuse into the red blood cell from the plasma as HCO3 – diffuses out
So, the correct option is D.( efflux ofHCO3- ionsfrom RBC)
