The correct answer is: A. Chisti.
Sharfuddin Maneri was a 13th-century Sufi saint who lived in Bihar, India. He was a disciple of the Chishti Sufi order, which is one of the most important Sufi orders in the world. The Chishti order is known for its emphasis on love, devotion, and service to others. Sharfuddin Maneri’s teachings have had a profound impact on the development of Sufism in India.
The Suhrawardi order is another important Sufi order, but it is not as closely associated with Sharfuddin Maneri. The Suhrawardi order is known for its emphasis on gnosis and intellectual understanding. Firdausi was a Persian poet who is not known to have been a Sufi saint. Kubrawi is another Sufi order, but it is not as well-known as the Chishti order.
In conclusion, the correct answer is: A. Chisti.
