The correct answer is Option 1- 1191

- Prithviraja III defeated Afghan ruler Sultan Muhammad Ghori in the First Battle of Tarain in 1191 CE. The battle took place near Tarain, which is located in present-day Haryana, India.

- The First Battle of Tarain was a significant conflict between the Rajput king Prithviraja III, the ruler of the Chauhan dynasty, and Sultan Muhammad Ghori, who was leading the Ghurid Empire.

- The battle was a result of the ongoing territorial and political rivalries in northern India during the medieval period.

- During the battle, Prithviraja III's forces displayed remarkable valor and strategic prowess, leading to a victory over Sultan Muhammad Ghori's forces. However, this victory was short-lived, as Ghori regrouped and returned for a rematch the following year.
