When the ghaznavids invaded the indian subcontinent what happened to the hindu society?

it disappeared
it went underground
it assimilated into the prevailing muslim culture
it remained distinct enough to carry on

The right answer is it assimilated into the prevailing Muslim Culture.

The first Muslim attacks on the subcontinent were made by Arabs on the western coast of Sind during the seventh and eighth centuries. Since that time there were communities of Arab merchants in India. However, the significant and permanent movement of Muslims in North India dates back to the late 12th century and was taken over by the Turkish dynasty that emerged indirectly from the ruins of the Abbasid caliphate. The route to the conquest was prepared by Sultan Mahmud of Ghazna, who conducted more than twenty attacks to the North of India between 1001 and 1027 and established in Punjab the easternmost province of his great but short empire. Mahmud's attacks, militarily successful, had as their primary objective the looting and not the conquests, and thus making assimilation of the Muslim culture of the invaders.
