Which of these is not an Indian Musical Instrument?

The Madal is primarily a traditional folk musical instrument of Nepal, though it is also popular in certain Himalayan regions of India (like Sikkim and Darjeeling) with Nepali culture. However, compared to classic indigenous instruments of mainstream Indian origin like the Sitar, Bansuri, and Tanpura, the Madal is distinctly classified as the national instrument of Nepal.
