Answer:

<em><u>The correct option is D) The two species have a common ancestor</u></em>

Explanation:

In evolutionary studies, homologous structures can be described as structures which are similar in organisms of different species because they had a common ancestor in the past. These structures may not perform the same function but are similar because they arose from a common ancestor.

The OH on the lower right of lysine and the H on the lower left of valine combine to form a molecule of water (H2O) and detach in a process known as a dehydration reaction when the two amino acids bond.
