Temple festivals are often accompanied by performances of traditional art forms like:

Kathakali
Panchavadyam
Sopana Sangeetham
All of the above

The correct answer is: D) All of the above.

Kathakali is a classical Indian dance-drama form that combines dance, music, and storytelling. It is known for its elaborate costumes, makeup, and stylized movements. Kathakali is performed in temples and other public spaces, and is often accompanied by music and singing.

Panchavadyam is a traditional South Indian percussion ensemble that consists of five instruments: the maddalam, the edakka, the chenda, the irumudi, and the thavil. Panchavadyam is often used to accompany temple festivals and other religious ceremonies.

Sopana Sangeetham is a genre of Carnatic music that is traditionally performed on the steps of a temple. Sopana Sangeetham is characterized by its use of simple melodies and lyrics that are easy to understand and sing along to.

All three of these art forms are often performed at temple festivals. They are all important parts of Indian culture and tradition, and they help to create a festive and celebratory atmosphere.
