Answer:
Option B, Snakes and lizards share a common ancestor.
Explanation:
From the description provided, it is clear that both the lizard and snake (including pythons) have evolved from the same ancestors which had hind legs. Since both the organism (i.e lizard and snake) underwent evolution (differently) for million of years such that the hind legs in lizard are visible and used even today but the hind legs in snakes are buried in muscles toward their tail ends and are not used. Such features which are not used at all or are poorly used are called as vestigial organs.
Hence, option B is correct
Proteins
Enzymes are proteins that can lower activation energy of reactions in the body (I think).
