Correct Answer: C
Explanation:
Since "No dogs are blue" is the same as " All dogs are not pink" it is the same in form as the first premise ("All politicians are dishonest") in Choice C. The second premise ("That animal is not blue") and the conclusion ("It must be a dog") are analogous to the second premise and the conclusion in Choice C. Choices A, D and E are incorrect if only because they represent valid arguments. Choice B represents an argument from probability which is, in any case, unlike the argument of the question.
