The correct answer is (a) Pullela Gopichand.
The World Beneath His Feet is a 2018 biography of Pullela Gopichand, an Indian badminton player who was the first Indian to win the All England Open Badminton Championships. The book was written by journalist Vijay Lokapally and published by HarperCollins India.
The book chronicles Gopichand’s life from his childhood in Hyderabad to his rise to become one of the world’s best badminton players. It also discusses his struggles and challenges, both on and off the court.
The book has been praised by critics for its insights into Gopichand’s life and career. It has also been a commercial success, selling over 100,000 copies in India.
The other options are incorrect because they are not the subjects of the book The World Beneath His Feet.
