(B) "model"
Dogs are implied to be a "model" or perfect example of faithfulness and obedience when Darwin refers to them as "the exact kind of fidelity and obedience." The answer is not (A). Although it is true that dogs represent "fidelity and obedience," it is absurd to say that they are a "category" or division of certain behavioural qualities. The answer is not (C). Even if Darwin seems to suggest that dogs exhibit particular characteristics, it would be absurd to say that they constitute a "designation" or label for "fidelity and obedience." The answer is not (D). Although dogs may have had a "role" in Darwin's views about animal intelligence, saying that they play a "very role" in specific behavioural features would be illogical. The answer is not (E). In this context, the word "figure" is not utilized.
