The bone patterns in mammalian limbs can be further traced to the bone structure of the Xenarthra species as far as its histology is concerned. There has been a bone compactness showing pattern most specifically in the femur area between the species of Cingulata and Pilosa.

Answer:
Carbon can bond with many elements
Explanation:
Carbon can bond with many elements, including itself, to form macromolecules. Moreover, it can form four bonds, and that makes possible many different arrangements of the atoms in the molecules.

C is <em>wrong</em>. Carbon is found in living things because it can form macromolecules, not the other way around.
D is <em>wrong</em>. Carbon can bond with many other elements beside itself.
