Vedclass · Answer

(A) When people migrate from plains to high-altitude areas like Rohtang Pass,the atmospheric pressure decreases,leading to lower oxygen availability (hypoxia). To compensate,the body undergoes acclimatization by increasing the production of $RBC$s to carry more oxygen and decreasing the binding affinity of hemoglobin to $O_2$ (shifting the oxygen-hemoglobin dissociation curve to the right),which facilitates the release of oxygen to the tissues. $A$ period of six months is sufficient for the body to adapt to these changes. Therefore,the correct option is $A$.
