Answer & ExplanationAnswer: [A]
The correct answer is Mahabalipuram.
Mahabalipuram, also known as Mamallapuram, is the best example of ratha temples. The ratha temples at Mahabalipuram are rock-cut monolithic structures that resemble chariots. They are named after the five Pandava heroes of the Mahabharata: Draupadi, Arjuna, Bhima, Nakula, and Sahadeva. These ratha temples are a significant architectural and artistic achievement of the Pallava dynasty and showcase their skill in rock-cut architecture.
Narttamallai, Kumbakonam, and Gangaikondacholapuram are notable temple sites in Tamil Nadu, but they are not specifically known for their ratha temples.
