Concept:Tat Vadya refers to string instruments where sound is produced by vibrating strings. They are also called chordophones.
Explanation:Indian musical instruments are classified into four categories based on how they produce sound.
Tat Vadya (chordophones) include instruments like sitar, veena, and sarod where strings are plucked, bowed, or struck.
Dilruba is a bowed string instrument with metal strings and a soundbox covered with goatskin. It is played with a bow and belongs to the Tat Vadya category.
Flute is a wind instrument (Sushira Vadya) and not a Tat Vadya.
Dandia are wooden sticks struck together in folk dance; they are Ghan Vadya (idiophones), not Tat Vadya.
Para is a traditional drum (Avanaddha Vadya or membranophone), not a Tat Vadya.
Therefore, among the given options, only Dilruba is a Tat Vadya.
