Solution

The correct option is A Aves

Birds have pneumatic bones. Pneumatic bones are basically long hollow bones that have air inside of them. These bones are interconnected via passages and are a characteristic feature of avians. They aid birds by reducing their weight which ultimately works in their favor while flying

So, the correct answer is 'Aves'
