How do humans acclimatise at high altitudes where atmospheric pressure is low for normal breathing?

A

By decreasing red blood cell production, decreasing the binding affinity of haemoglobin and by increasing breathing rate

B

By increasing red blood cell production, decreasing the binding affinity of haemoglobin and by increasing breathing rate

C

By hibernating

D

By increasing white blood cell production, decreasing the binding affinity of haemoglobin and by increasing breathing rate
