The correct option is C pCO2 increases and pO2 decreases
Bohr's effect refers to loss of affinity for oxygen with decreasing pH (increasing acidity) , occurs in microcirculation as oxygen is consumed and carbon dioxide is released by tissues.Carbon dioxide reacts with water to form carbonic acid , increase in CO2 concentartion results in decrease in blood pH, resultinng in haemoglobin proteins releasing their load of oxygen
