Correct Option: B

The most influential musician of the Delhi Sultanate period was Amir Khusrau (1253–1325), sometimes called the father of modern Hindustani classical music. A composer in Persian, Turkish, Arabic, as well as Braj Bhasha, he is credited with systematizing many aspects of Hindustani music, and also introducing several ragas such as Yaman Kalyan, Zeelaf and Sarpada. He created the qawwali genre, which fuses Persian melody and beat on a dhrupad like structure. A number of instruments (such as the sitar and tabla) were also introduced in his time. Amir Khusrau is sometimes credited with the origins of the khyal form, but the records of his compositions do not appear to support this.
