Explanation:

Shiva (Correct): The Rajarajeshwara Temple, more commonly known as the Brihadeeswarar Temple, is a magnificent Hindu temple located in Thanjavur (Tanjore), Tamil Nadu. It was built by Raja Raja Chola I between 1003 and 1010 CE and is dedicated to Lord Shiva. The temple is famous for its massive Shiva Lingam and is a UNESCO World Heritage Site, renowned for its Dravidian architecture. Vishnu: While a major Hindu deity, the Brihadeeswarar Temple is explicitly a Shaivite temple, dedicated to Lord Shiva. Surya: Surya, the Sun God, is worshipped, but this temple is not dedicated to him. Indra: Indra is an ancient Vedic deity, rarely the primary deity of major temples in Dravidian architectural style, and certainly not of the Brihadeeswarar Temple.
