When exposed to high-altitude hypoxia, where oxygen levels are lower, the body undergoes several adaptations to ensure adequate oxygen supply to the tissues. One of these adaptations is the increased production of red blood cells, a process known as erythropoiesis. Erythropoiesis is regulated by the hormone erythropoietin (EPO), which is released by the kidneys in response to low oxygen levels. EPO stimulates the bone marrow to produce more red blood cells. By increasing the number of red blood cells, the body can transport more oxygen to the tissues, compensating for the lower oxygen availability at high altitudes.

Hence, the correct answer is option 1.
