South African Olympic champion in the 800 m with higher testosterone levels than typical female athletes; refused to comply with hormone reduction rules.

• A. Bobby Riggs
• B. Wilma Rudolph
• C. Harry Edwards
• D. Caster Semenya

Answer: (D)

The situation tests how biology and sport eligibility intersect, specifically how testosterone levels can influence who is eligible to compete in certain female events and how athletes respond to those rules. Caster Semenya is the South African Olympic champion in the 800 meters who has higher testosterone levels than many of her female peers. This led to regulatory rules about testosterone in female competition, and she refused to comply with the hormone-reduction requirements, challenging the policy. The other names listed aren’t linked to this scenario—Bobby Riggs was a male tennis player, Wilma Rudolph was known for sprinting events, and Harry Edwards is a sociologist and activist.
