The correct answer is D) Prince Dara Shikoh. François Bernier, a French physician and traveller, came to India in 1658 and resided at the Mughal court for about twelve years. He initially served as a physician to Prince Dara Shikoh, the eldest son of Emperor Shah Jahan. After Dara Shikoh’s defeat and execution, Bernier managed to gain favour with Aurangzeb, the new emperor, and also served Danishmand Khan, a Mughal noble. His book, ‘Travels in the Mogul Empire’, is a valuable account of life, society, and politics in India during the Mughal period.
