A) people get pollution-free air to breathe and more oxygen is available
B) atmospheric \[{{O}_{2}}\] level is less and hence more RBCs are needed to absorb the required amount of \[{{O}_{2}}\] to survive
C) there is more UV radiation which enhances RBC production
D) people eat more nutritive food, therefore more RBCs are formed
Correct Answer: B
Solution :
At high altitudes, the atmospheric \[{{O}_{2}}\] level is less and hence, more RBCs are needed to absorb the required amount of \[{{O}_{2}}\] to survive. That is why, the people living at sea level have around S million \[RBC/m{{m}^{3}}\] of their blood whereas those living at an altitude of 5400 meters have around 8 million \[RBC/m{{m}^{3}}\] of their blood.
