The correct answer is option 1, Mahmud of Ghazni. Mahmud of Ghazni, who was the ruler of the Ghaznavid Empire, attacked the Somnath temple in Gujarat, India. He launched a series of raids on the temple in the early 11th century. Mahmud was driven by both religious motivations and the lure of wealth that the temple possessed. He believed that by plundering and destroying the Hindu temple, he would be able to establish his authority and spread Islam in the region. Mahmud`s repeated attacks on the Somnath temple and other Hindu temples earned him a notorious reputation as a temple destroyer. It is important to note that while Muhammad Ghori, Iltutmish, and Qutbuddin Aibak were also prominent Muslim rulers in India, they were not directly responsible for the attack on the Somnath temple.
