From the figure, it can be inferred that both Dryopithecus and Ouranopithecus were great apes (choice 1). They appear to be part of a polytomy, as indicated by the branches merging together (choice 3). Their closest common ancestor with all of the extant great apes is the one they share with the orangutans (choice 4). However, there is no information given in the figure about the genetic differences between Dryopithecus and Ouranopithecus, so choice 5 cannot be inferred. It is also mentioned in the figure that Dryopithecus and Ouranopithecus shared a common ancestor more recently with the orangutans than with the other great apes (choice 2). Therefore, the best choice is B.
