In which year did Steffi Graf win the Golden Slam?
A
Correct answer
Explanation
Steffi Graf achieved the Golden Slam in 1988 by winning all four Grand Slam titles (Australian Open, French Open, Wimbledon, and US Open) plus the Olympic gold medal in the same calendar year. This is one of the greatest achievements in tennis history and has never been duplicated. The other years listed are incorrect as her Golden Slam was specifically in 1988.
