Answer 1

The correct option is D syrinx

Larynx is the voice box inside human neck, which produces sound. Vocal cords are found inside larynx, and frequency of sound generated depends upon the thickness of vocal cords. Glottis makes several voicing sounds between the vocal folds, when they vibrate. So option (A), (B) and (C) can't be the answer.

Syrinx is the vocal organ of birds which produces the sound in birds . So option (D) is correct.
