Answer: C

A lack of sufficient red blood cells or haemoglobin is anemia.

Anemia reduces the oxygen-carrying capacity of the blood, causing fatigue, breathlessness and poor endurance. Iron deficiency is the commonest cause, and athletes, especially women, are at risk.

An aneurysm is a balloon-like swelling of a weakened artery wall. An androgen is a male sex hormone such as testosterone. Apnea is a temporary stopping of breathing, as in sleep apnoea.
