The passage suggests that a finely developed sense of grievance is something that other animals would not be capable of, implying that it is more developed in humans. Option B is incorrect because the passage suggests a difference in the development of this sense between humans and other animals. Option C is incorrect because the passage does not state that the sense of grievance is absent in other animals, only that it is not as finely developed. Option D is incorrect because the passage suggests the opposite, that this sense is more developed in humans.
