Dilip Kaur Tiwana is a renowned Indian author, thus the correct answer is Option 1 - litterateur. She is known for her contributions to the Punjabi literary world, where she wrote numerous novels, short stories and autobiographical accounts.
Option 2 lists her as a musician, which is incorrect. There are no credible sources indicating that Dilip Kaur Tiwana is known for her musical abilities or contributions.
Option 3 labels her a scientist, which is again untrue. While she made significant contributions to the field of literature, there is no record of her having worked in any scientific field.
Option 4 identifies her as a sports person, which is also not the right answer. Dilip Kaur Tiwana has not been associated with any sports activities or events, professionally. Hence, her renowned image is purely as a litterateur.
