Option b is the correct answer. Akbar was the Mughal emperor who ruled from 1556 to 1605. He was known for his religious tolerance and his reforms in administration, taxation, and culture. He founded the Din-i Ifehi (Divine Monotheism) or Divine Faith, in 1582 as a new syncretic religion or spiritual program that combined elements from various religions, such as Islam, Hinduism, Jainism, Sikhism, Christianity, Zoroastrianism, and Buddhism. Important Tips The Dīn-i Ilāhī was not a popular or widespread religion, but rather an elite eclectic movement that never numbered more than 19 adherents. The members of the religion were handpicked by Akbar according to their devotion to him. They included some of his closest friends and advisers, such as Abu'l-Fazl, Birbal, Faizi, and Abul Faizi Sirhindi. The Dīn-i Ilāhī did not survive Akbar's death in 1605 and was soon forgotten. Akbar established Ibadat Khana as a house of worship at Fatehpur Sikri in 1575. He issued an Infallibility Decree in 1579, which asserted his religious authority over his subjects. It stated that Akbar had the power to interpret the Islamic law and issue binding judgments on religious matters.
