Option c is the correct answer. Statement I is incorrect: Tansen' was not the title given to Rambali Pandey by Akbar, but by Raja Ramchandra Singh of Rewa, who was his patron before he joined Akbar's court. Akbar gave him the title of Mian, meaning learned man. Statement II is incorrect: Akbar was not married with the sister of Raja Man Singh, but with the daughter of Raja Bharmal of Amber, who was Man Singh's grandfather. Her name was Mariam-uz-Zamani, and she was also known as Jodha Bai. Statement III is correct: Abul Fazl was the author of Ain-i-Akbari, which was the third volume of his magnum opus, the Akbarnama. The Ain-i-Akbari was a detailed account of Akbar's administration, policies, culture, religion, army, geography, and biography. It also contained a comprehensive description of the Mughal Empire and its provinces. Statement IV is incorrect: Raja Todarmal was finance minister Akbar and one of the Navaratnas (nine jewels) of his court. He introduced a new system of land revenue collection and assessment known as zabt or dahsala.
