The correct answer is: a) Cymbals.
Cymbals are a type of percussion instrument that is common in many cultures around the world. They are made of two metal plates that are struck together to produce a loud, ringing sound. Cymbals are often used in religious ceremonies and rituals, and they are also used in a variety of musical genres, including classical, jazz, and rock.
In Sikkim, cymbals are an important part of the Buddhist tradition. They are used in religious ceremonies and rituals, and they are also used in traditional Sikkimese music. Cymbals are often played in pairs, and they are struck together in a variety of patterns to create different sounds.
The other options are incorrect because they are not common musical instruments in Sikkim’s Buddhist tradition. A piano is a keyboard instrument that is popular in Western culture. A guitar is a stringed instrument that is popular in many cultures around the world. A violin is a stringed instrument that is popular in Western classical music.
