The instrument which does not have leather?

Question

Accepted Answer

The correct option is 4:
The correct option is Mendolin (Mandolin), as this instrument is constructed entirely of wood and strings, without the use of an animal hide or leather membrane. The Mendolin is classified as a plucked string instrument from the lute family, and its sound is produced by the strings vibrating over a solid, usually flat or slightly arched, wooden soundboard. This all-wooden construction, which features soundholes but no stretched skin for resonance, is consistent with instruments of Western origin and makes it the clear exception among the choices, as it contains no leather component in its main body structure.

The incorrect options are 1, 2, and 3:
The instruments Dilruba, Sarod, and Sarangi are all traditional Indian string instruments, and a key feature of their construction is the use of stretched animal skin or leather to cover their resonance chambers. The **Dilruba** and the **Sarangi** are bowed instruments whose main body, carved from wood, is covered with a parchment, typically made from goat skin. The bridge rests directly on this stretched skin, which is vital for amplifying the sound. Likewise, the **Sarod** is a plucked instrument that also utilizes a membrane of animal skin, usually goat skin, which is tightly stretched over the face of its hollow resonator. This leather membrane in the Sarod plays a critical role in shaping its unique, skin-headed tone and characteristic resonant decay. Therefore, all three of these instruments contain leather as a necessary and functional part of their design, making them incorrect answers.
