Biology

The correct explanation is: A.DNA is in all living organisms & suggests that we all evolved from a common ancestor.

Explanation:

DNA provides strong evidence for evolution because it is found in all living organisms, and the similarities and differences in the DNA sequences of different species can show how closely related they are. Species that share similar DNA sequences likely evolved from a common ancestor. The more closely related two species are, the more similar their DNA will be, supporting the idea of shared ancestry and evolutionary relationships.

1.DNA is in all living organisms: All life forms use DNA as their genetic material, which is a fundamental similarity that points to a common origin.

2.Suggests that we all evolve...
