Question

Hood of cobra is formed by __________________.

• A. Elongation of muscles
• B. Contraction and flattening of neck
• C. Spreading of ribs of neck region
• D. Both A and B

Answer 1

The correct option is C Spreading of ribs of neck region

The cobra's hood is created by many elongated ribs that are capable of extending the looser skin on the neck outwards. The cobra rises up on the forward portion of its body and flattens its neck, spreading out this skin on the ribs to create what appears to be a hood. Hence the correct option is C.
