<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. Hence, the bone in a bird's wing can be homologous to a bone in a lizard leg because they have a common ancestor in the past.
