Answer 2

The correct answer is - Snakes have tiny internal hind leg bones, indicating that they likely descended from lizards.

Step-by-step explanation:

Minimal structures are the structures in a life form which are not, at this point being used. In past these minimal structures played out some significant capacities in those life forms however bit by bit because of development now they have become non utilitarian in their body.

Reptiles and snakes both are reptiles yet reptiles have a practical rear appendage which causes them in slithering, snakes have been developed from reptiles however so as to move they creep instead of creeping so their rear appendage doesn't serve any capacity in development. Rear appendages are available in their body as a minimal organ.

Thus, The correct answer is - Snakes have tiny internal hind leg bones, indicating that they likely descended from lizards.
