Explanation:

Let’s break it down:

- Plate instrument: These are typically instruments that involve striking or scraping a flat solid object—think xylophones or gongs. 'Chinkara' doesn’t fit here.

- Wind instrument: These are things you blow into—flute, shehnai, clarinet. Chinkara is not in this group.

- Stringed instrument: Instruments with strings you pluck, bow, or strum. Sitar, violin, guitar—Chinkara slots right in here.

- Membrane instrument: Drums and tablas—basically, anything where you beat on a stretched skin. Again, not what we’re talking about with Chinkara.

So yes, the correct answer is:

Option 3: stringed.
