Option 1 -> This refers to the First Battle of Panipat (1526), not the Battle of Tarain.
Option 2 -> The First Battle of Tarain (1191 CE) was fought between Prithviraj Chauhan, the Chahamana ruler of Ajmer and Delhi, and Muhammad Ghori, the Ghurid Sultan.
Option 3 -> This refers to the Battle of Haldighati (1576), not the Battle of Tarain.
Option 4 -> This refers to the Battle of Chausa (1539) or Battle of Kannauj (1540), not the Battle of Tarain.
Hence, Option 2: Prithviraj Chauhan and Muhammad Ghori -> The First Battle of Tarain was fought in 1191 CE near Tarain (modern-day Haryana). Prithviraj Chauhan decisively defeated Muhammad Ghori in this battle. However, Ghori returned the following year and defeated Prithviraj in the Second Battle of Tarain (1192), which marked a turning point in Indian history -> correct
