    The only reptiles that have specially adapted jaws to be able to swallow eggs or prey much larger in diameter than themselves are.

    A)  Tortoises          

    B)  dragon lizards

    C)  Monitor lizards

    D)  snakes

For example, the African egg-eating snake has flexible jaws adapted for eating eggs much larger than the diameter of its head.
