Question

Which of the following is not detectable in birds?

• A. Pectoral girdle
• B. Pelvic girdle
• C. Forelimbs
• D. Hindlimbs

Answer 1

The correct option is C Forelimbs

Birds are vertebrates possessing a vertebral column, a hollow dorsal nerve cord and pharyngeal gill slits at some stage of their life. They have two pairs of limbs out of which the forelimbs are modified into wings. These wings are covered with feathers and are the main flying structure of the bird.

So, the correct answer is 'Forelimbs'.
