The figure shows a simplified phylogeny of the major groups of mammals. Eutheria and Mammalia are larger clades that include all the groups shown. Primates are a member of both Eutheria and Mammalia, while Monotremata are only a member of Mammalia. Rodents are a member of the Eutheria clade, but not the Carnivora clade. Felidae are a member of both the Carnivora and Theria clades. Therefore, the only statement that is true based on the given phylogeny is that primates are members of the Eutheria and Mammalia clades (option B).
