Show answer and explanation

Answer: C. Either I or II follows

Answer: C) Either I or II follows
Explanation: Conclusion I claims an affirmative relation (Some pens are pencils), and Conclusion II claims a negative relation (No pen is a pencil). They form a complementary pair (All/Some vs No) and neither is definitely proven by the basic statements, meaning either one or the other must be true, satisfying the "Either-Or" condition.
