To determine relatedness, scientists would likely examine multiple factors, including homologous structures (similar structures indicating a common ancestor), vestigial structures (structures that no longer serve a function but were present in an ancestor), and biogeography (the geographic distribution of organisms and their ancestors). Therefore, all of the choices could be examined to determine relatedness, making D the best answer.
