B) if only conclusion II follows

C) if either conclusion I or II follows

D) if neither conclusion I nor II follows

E) if both conclusions I and II follow

Answer:

Option B

Explanation:

Since both the premises are universal and affirmative, the conclusion must- be universal affirmative and should not contain the middle term. so, it follows that 'All pens are houses. II is the converse of this conclusion and so it holds. Since the term 'houses' is distributed in, I without being distributed in any of the premises so I do not follow.
