Solution

The correct option is C low concentrations of oxygen in the blood and tissues
Low concentration of oxygen in the blood and tissues of people living at high altitudes is due to low atmospheric pressure. Because at high altitude, the partial pressure of oxygen is less than at the ground level. This decreased atmospheric pressure causes release of oxygen from blood.
