Which one of the following is different from the rest?

The answer is A) Sarnath. The other three are famous battlefields, and Sarnath is not.

• Panipat (C) is a battle site in Haryana, known for three decisive battles: 1526 (Babur defeating Ibrahim Lodi), 1556 (Akbar against Hemu) and 1761 (Marathas under Sadashivrao Bhau losing to Ahmad Shah Abdali).
• Haldighati (B) is a mountain pass near Gogunda in Rajsamand district, Rajasthan, where Rana Pratap of Mewar fought Man Singh's Mughal army in 1576.
• Kurukshetra (D) in Haryana is the site of the Mahabharata war, and later of the 1014 Thanesar-era contests and the 1948 relief camps only in a historical sense; for this question, it is the classic battlefield of the epic.
• Sarnath (A), near Varanasi in Uttar Pradesh, is a Buddhist pilgrimage site where the Buddha gave his first sermon (Dharmachakra Pravartana). It has the Ashokan lion capital, which became the national emblem in 1950. It has no military significance.

The core concept is the identification of places by their historical role: religious, administrative or military. For Mains, Sarnath links to Ashokan Buddhism and the ancient art and architecture of the Gupta and Mauryan periods, while the battle sites link to medieval state formation and the contest for North India.

Trap: candidates often treat Kurukshetra as a non-battle site because of its religious and mythological image. Read the question for the common feature: all three others are places where armies fought.
