Who among the following Rajput rulers defeated Muhammad Ghori in the First Battle of Tarain in 1191 AD?

The correct answer is Prithviraj Chauhan.

Step-by-Step Explanation:
1. Historical Context: The Battles of Tarain were fought between the Ghurid ruler Muhammad Ghori and the Rajput Chahamana (Chauhan) king Prithviraj Chauhan near Tarain (modern-day Taraori in Haryana).
2. The First Battle of Tarain (1191 AD): In 1191 AD, Muhammad Ghori invaded the Chahamana territories and captured the fortress of Bhatinda. Prithviraj Chauhan mobilized his forces, including several vassal rulers, to confront the invader.
3. Outcome: In this battle, the Rajput forces led by Prithviraj Chauhan decisively defeated the army of Muhammad Ghori. Ghori himself was injured during the combat and had to be rescued, leading to the retreat of his forces.
4. Significance: This victory temporarily halted the expansion of the Ghurid Empire into northern India, although Muhammad Ghori returned the following year in 1192 AD to fight the Second Battle of Tarain.
