In the first Grand Slam of the year 2000, the player Martina Hingis defeated to reach the final was Serena Williams (option 3). Here is a breakdown of the other options. Option 1, Lindsay Davenport, was a strong player in this time period, however, she wasn`t the one Hingis defeated to get to the final. Option 2, Jennifer Capriati, although she was a competitive player and had some epic battles with Hingis, was not the one who faced Hingis in this particular Grand Slam. Option 4, Conchita Martinez, despite being a top-tier player in the women`s circuit at the time, was also not the player Hingis beat to reach the final. So, the correct answer is Serena Williams, one of the most iconic players in the sport of tennis, thus making the option 3 correct.
