The correct answer is: C. Mirwaiz Rasool.
Anjuman-i-Nusratul Islam was launched to promote education among illiterate Kashmiri Muslims by Mirwaiz Rasool in 1882. It was the first educational institution in Kashmir to provide free education to the poor. The Anjuman also played a significant role in the social and political development of Kashmir.
Hari Singh was the Maharaja of Jammu and Kashmir from 1846 to 1925. He was a Hindu ruler who did not take much interest in the education of the Muslim population of Kashmir. Pratap Singh was the son of Hari Singh and the Maharaja of Jammu and Kashmir from 1925 to 1947. He was also a Hindu ruler who did not take much interest in the education of the Muslim population of Kashmir.
Therefore, the correct answer is C. Mirwaiz Rasool.
