Vedclass · Answer

(C) In birds,the sternum is modified into a large,boat-shaped structure known as the $Keel$ or $Carina$.This structure provides a large surface area for the attachment of powerful flight muscles ($Pectoralis$ muscles).These muscles are essential for flapping the wings during flight.Therefore,the presence of a well-developed,boat-shaped sternum is a clear adaptation for strong flight capability.
