Correct Option: E
First Premise is Universal Negative (E-type).
Second Premise is Universal Affirmative (A-type).
No cow is chair. ↔ All chairs are tables.
E + A ⇒ O1 – type of Conclusion “Some tables are not cows.”
Conclusion I is Converse of the second Premise. Therefore, Conclusion I follows.
Conclusions II and IV form Complementary Pair. Therefore, either Conclusion II or IV follows. Thus, Conclusion I and Conclusion II or IV follow.
There is no such options.
