• A. Flightless bird
• B. Flying birds
• C. Both A and B
• D. None of the above

Answer 1

The correct option is A Flightless bird

Flightless birds are usually large birds adapted for walking and running. Syrinx is the sound organ found in some birds. It is well developed in the songbirds. Furcula or wishbone is a forked bone found in the birds. Pygostyle is the triangular plate that supports the tail feathers.

Syrinx, furcula and pygostyle are absent in flightless birds (ratitae). Hence, option A is correct.
