The Ghaznavids had as leader Mahmoud of Ghazni. He was an Afghan Islamic ruler. He was the first Islamist to invade India, in which he won a great battle against the Confederation of the Hindu states in 1008. His last attack resulted in the looting of the Hindu temple and its consequences of his attacks were the weakening of the power of Hindu rulers.
Mahmoud transforms Ghazni (its main city) into a large center of art and culture that has housed a large number of scholars and artists, including Al-Birouni. He founded a university, designed gardens and built mosques and palaces.
As we can see, the right answer is C, supported artists.
