C is correct: EPO stimulates red blood cell production, increasing the oxygen delivered to working muscles. The extra red blood cells thicken the blood, increasing the risk of clots, stroke and heart attack.

Other options:

A is incorrect: This describes anabolic steroids, which are used for strength and power.
B is incorrect: This describes diuretics, which increase fluid loss.
D is incorrect: This describes beta blockers, which are used in precision sports such as shooting.
