Answer 1

The correct option is D Both A and B

Syrinx

Syrinx is the vocal organ present in the birds. It is a bony structure which produces sound by the vibration of its walls during the flow of air.

Thus, sound is produced in birds through the operation of a voice box.

Vibrating bone

Sound is produced in birds due to the vibration of the walls of syrinx as well as pessulus.

The latter is a delicate cartilaginous structure which serves as a connecting structure in the syrinx.

Final answer

(d) Both A and B
