Answer : 2. "बौद्धों का"
Explanation :

‘Muhammad bin Qasim’ was a young Arab commander. He was sent by Al-Hajjaj, the governor of Iraq, who was also the uncle and father-in-law of Muhammad bin Qasim, to punish Dahir, the ruler of Sindh. Neun was located near Charak, south of present-day Hyderabad in Pakistan. After Deval, Muhammad Qasim proceeded to conquer Neun. Dahir handed over the responsibility of protecting Naun to a priest and called his son Jai Singh to Brahmanabad. The number of Buddhists was high in Neun. He welcomed Muhammad bin Qasim. In this way, without fighting, Mir Qasim gained control over the Neun fort.
