Option (c) is correct because the Ibadat Khana (House of Worship) was established by Akbar in 1575 at Fatehpur Sikri specifically as a forum for theological debates with scholars of various faiths, including Hinduism, Islam, Christianity, and Jainism. Option (d) is the most tempting distractor, but it is incorrect because the primary participants were religious theologians and scholars rather than just nobles, and the discussions were presided over by Akbar himself to seek religious truth. This question tests the core concept of Akbar’s evolving religious policy and his pursuit of universal peace (*Sulh-i-kul*) through intellectual inquiry.
