Which of the following temple is located at Belur?

The correct answer is Option 2 - Chennakeshava temple

Some of the areas that were incorporated within the Vijaynagar empire had witnessed the development of powerful states such as those of the Cholas in Tamil Nadu and the Hoysalas in Karnataka. Ruling elites in these areas had extended patronage to elaborate temples such as the Brihadishvara temple at Thanjavur and the Chennakeshava temple at Belur. The rulers of Vijayanagara, who called themselves rayas, built on these traditions and carried them, as we will see, literally to new heights.
