The correct statements about the Chausath Yogini Temple are 1 and 4. Built during the Kachchhapaghata Dynasty, the temple features a circular design, which is significant in showcasing the architectural evolution of Indian temple design. Statement 4 is also valid as the circular form of the temple has inspired various architectural elements, including the design of the Indian Parliament building, emphasizing the enduring influence of historical architecture on modern civic structures. Notably, statement 2 is incorrect since while the Chausath Yogini Temple is one of the few circular temples, it is not the only one in India. Additionally, statement 3 is not accurate; the temple primarily served as a site for Shakti worship, rather than promoting the Vaishnava cult.
