b. Organgutans and gorillas are more closely related than humans and gorillas
Explanation:
We need to take a look at the internet and get a family tree for all the great apes. I searched one and I will upload it so you can check it when you need it. That tree is all what you need to rule out incorrect options. Option a is not correct because the tree shows orangutan is not the common ancestor of all great apes; we can also discard the idea of the gorila being a common ancestor to humans, chimps and bonobos because gorilla actually shares a common ancestor with all of them, so option c is not correct. Basically it all comes down to review the family tree and you will also see humans and gorillas are not more closely related than orangutans and gorillas. Option d is ruled out as well. And what about option e? Well, that is the only one that does not required the family tree. Upraight gait is a human characteristic and this why option e is false. So the winner is option b and can be double-checked by looking and the family tree.
