Which of the following dance form was earlier known as Daasiyattam?

The correct answer is Option (3) → Bharatnatyam

Bharatanatyam, the classical dance of Tamil Nadu, was performed for centuries in temples by the devadasis, and was therefore called Dasiattam (Daasiyattam), the dance of the dasis; it was also known as Sadir. In the 1930s reformers such as E. Krishna Iyer and Rukmini Devi Arundale brought it to the public stage under the new name Bharatanatyam.
