Which two of the following changes (a-d) usually tend to occur in plain dwellers when they move to higher altitudes (3500m or more)?

(d) Increase in thrombocyte count
Which two of the following changes (a-d) usually tend to occur in plain dwellers when they move to higher altitudes (3500m or more)?
(a) Increase in red blood cell size
(b) Increase in red blood cell production
(c) Increase in breathing rate
(d) Increase in thrombocyte count
The correct option is D B and C
When a plain dweller moves to a higher altitude (3500m or above) then
altitude sickness occurs. The symptoms include nausea, fatigue, and
heart palpitations because of low atmospheric pressure and the
inability of the body to take enough oxygen. Thus, to cope up with
this body shows Physiological adaptation which includes-
1) Increase in RBCs production
2) The decrease in binding capacity of hemoglobin
3) By increasing the breathing rate
Thus, considering the statements given statement (b) and (c) are
correct.
So, the correct answer to the question is 'B and C'.
