The correct answer is: D. None of the above.
Kabir was a 15th-century Indian mystic poet and saint. He is considered to be one of the most important figures in the Bhakti movement, which emphasized the importance of devotion to God over ritual and caste. Kabir was born into a Muslim family, but he was attracted to Hindu teachings. He eventually became a disciple of Ramananda, a Hindu saint who preached a message of religious tolerance and equality.
Ramanujacharya was a 12th-century Hindu philosopher and theologian. He is considered to be one of the most important figures in the Sri Vaishnava tradition. Ramanujacharya’s teachings emphasized the importance of devotion to Vishnu, the supreme god in the Vaishnava tradition.
Shakracharya was a 10th-century Hindu philosopher and theologian. He is considered to be one of the most important figures in the Advaita Vedanta tradition. Shakracharya’s teachings emphasized the unity of the individual soul with Brahman, the ultimate reality.
In conclusion, Kabir was not a disciple of any of the three figures mentioned in the question. He was a disciple of Ramananda, a Hindu saint who preached a message of religious tolerance and equality.
