Answer & Explanation

Answer: [B]

The battle of Koppan, also known as the Battle of Koppam, took place in the 11th century CE in South India. It was a significant military confrontation between the Chola dynasty, a powerful dynasty in Tamil Nadu, and the Hoysala dynasty, a prominent dynasty in Karnataka. The Cholas and Hoysalas were two major regional powers during that period, and the battle of Koppan was a result of territorial disputes and power struggles between the two kingdoms.

Therefore, the battle of Koppan was fought between the Cholas and the Hoysalas, not the Western Chalukyas and the Pallavas or any other combinations mentioned.
