The best technique for determining the evolutionary relationships among closely related species that still have living members is **d) DNA or RNA analysis**.
While homologous structure analysis, comparative anatomy, and comparative embryology can provide valuable insights into evolutionary relationships, molecular techniques such as DNA or RNA analysis are often more precise and provide a clearer picture of genetic relatedness. Molecular data allows researchers to assess genetic similarities and differences on a much finer scale, which is particularly useful for closely related species.
