What logical scientific inference can be drawn from the observation that many different species have homologous structures?

a) different species always use similar structures for the same purpose.
b) there are only a limited number of ways organisms can evolve.
c) all species with similar anatomical structures are related.
d) related species have similar structures that have been modified through evolution.

Option C) All species with similar anatomical structures are related.

Explanation:Homologous Structure: A homologous structure is an example of an organ or bone that appears in different animals, which are anatomically similar structure demonstrating descent from a common ancestor.All species with similar anatomical structures which means they have  homologous structures and are related as they have evolved from a common ancestor.Homologous structures shows divergent evolution.

Result: Option C is the correct scientific inference for homologous structures.
