Correct Answer: (d) Ahmadnagar Fort Jail
Solution:Jawaharlal Nehru wrote the book “The Discovery of India” during his imprisonment at Ahmadnagar Fort Jail. The journey in The Discovery of India begins from ancient history, leading up to the last years of the British Raj. Nehru uses his knowledge of the Upanishads, Vedas, and textbooks on ancient history to introduce to the reader the development of India from the Indus Valley civilization, through the changes in socio-political scenario every foreign invader brought, to the present day conditions. Nehru was jailed for his participation in the Quit India Movement along with other Indian leaders, and he used this time to write down his thoughts and knowledge about India's history. The book provides a broad view of Indian history, philosophy, and culture as viewed from the eyes of an Indian fighting for the independence of his country.
