As learnt in

Relation between pressure and concentration -

$PV=nRT$

$or\:P=\frac{n}{V}RT$

$or\:P=CRT$

$R=0.0831\:bar\:inter/mol\:K$

- wherein

P is pressure in Pa. C is concentration in mol / litre. T is temperature in kelvin

At higher altitudes, the pressure decreases causing a lowering in concentration of oxygen in the blood as P =CRT

Option 1)

Low temperature

Incorrect

Option 2)

Low atmospheric pressure

correct

Option 3)

High atmospheric pressure

Incorrect

Option 4)

Both low temperature and high atmospheric pressure

Incorrect
