The correct answer is "1 and 3 only" because Manipuri Sankirtana is indeed a vibrant performance that integrates both song and dance, deeply rooted in the Vaishnava tradition, particularly to narrate the life and deeds of Lord Krishna. However, the assertion that cymbals are the only musical instruments used is incorrect; in fact, Manipuri Sankirtana typically features a variety of instruments, including the traditional Manipuri drum known as "dhol" and other percussion instruments. This distinction is crucial for understanding the cultural and artistic diversity of Indian classical performances, which is often emphasized in UPSC examination materials.
