Similarity between DNA sequences of two eukaryotic species is used to predict their evolutionary relatedness, pointing to a shared ancestry. In an attempt to evaluate this relatedness, a group of researchers sequenced and compared two proteins with the same function from the two species. The corresponding DNA and RNA sequences were also compared to decipher their relatedness. Based on this information, the correct option is
