Answer:
C. The fossilized remains of giant sloths were found in places where smaller sloths now live.
F. The bony shells of armadillos resembled the shells of ancient Glyptodon fossils.
Explanation:
Relationships between existing and living species occur when they share some sort of similarity in their anatomy, internal biological structure and DNA structure. In both option C and F some sort of resemblance between the existing and previous species form has been established. Thus, these two options are correct.
However, in option A, B, D and E no such relationship has been established.
I do not know the options, but, follow this criteria and you should be able to finish the exercise:
Usually, animals that are in captivity are endangered animals, with few individuals left. When we captivate them, the risks of them dying (either naturally or by poaching, hunting, contamination, etc) is lower, since we are taking direct care of them.
Hope it helped,
