Answer: 1. Neophron

Birds have light, hollow bones with air cavities (pneumatic bones) to help flight.

Neophron (vulture) is a bird, so it has pneumatic long bones. Hemidactylus (wall lizard, reptile), Macropus (kangaroo) and Ornithorhynchus (platypus, mammals) have solid, marrow-filled long bones.
