Correct answer: C
Correct choice: the statements "Predicate of the conclusion is distributed" and "Middle term appears as a predicate in the major premise" are correct. Explanation: Placement of the middle term in the fourth figure: the middle term is the predicate in the major premise and the subject in the minor premise.
Major premise is an E proposition (No A is B). In E propositions both subject and predicate are distributed, so the middle term (being the predicate in the major) is distributed. Therefore the statement claiming an undistributed middle term is false.
Conclusion is an O proposition (Some A is not C). In O propositions the predicate is distributed while the subject is not. Hence the predicate of the conclusion is distributed, so the claim that the conclusion distributes none of its terms is false.
Putting this together: the two true statements are (1) the middle term appears as a predicate in the major premise, and (2) the predicate of the conclusion is distributed. The other listed statements are incorrect for the reasons above.
