您好。看起来答案是A没错。不妨看看我的分析：
答案选项B,C&D 不逻辑。
B：'was defeated in her most recent tournament ', 最后一段第一行有提及：‘Although Emily Toner bounced back to win the Paris Open this month, ...', 划线部分说明了Emily Toner 在近期赢了比赛，不是被打败。此答案不成立。
C: 'won against Walters in the Olympics.', 虽然第二段里，这报导使用 'The Olympic champion' 来称呼Emily Toner，但并没有明确说明她曾在奥运里击败过Walters， Walters是否有参与过奥运也不一定，所以答案不成立。
D: 'lost the last time she played in Delhi.', 在第一段第一句里提到 ‘Emily Toner, is about to make her first appearance in the Delhi Open...'，划线部分说明了Emily是第一次在Delhi 亮相，所以答案不成立。
最合适答案为A： 'is keen on beating her rival at the Delhi Open.'
原因：最后一段提到，‘...she is looking to get even with Walters, a player she has lost to just twice in 27 meetings.', 划线部分说明她期望把Walters也打败，后半句里也不明确地暗示了Emily不想输给自己一直以来的手下败将。
