The correct answer is: B.Similar DNA sequences in closely related species.

Explanation:

One of the key pieces of molecular evidence supporting the theory of evolution is the observation that closely related species share similar DNA sequences. This suggests that they have a common ancestor and have diverged over time. The more similar the DNA sequences, the more closely related the species are, providing evidence for evolutionary relationships.

Here’s why the other options don’t fit:

A.Identical protein structures in all living organisms: While many proteins are similar across species, there are differences in protein structures t...
