Show answer & explanation
Correct answer: B
Step 1: Analyze Statement II ("No J are W"). This means the circles for J and W are completely separate and do not touch. Therefore, Conclusion I ("Some J are W") is completely false.
Step 2: Analyze Statement I ("Some W are K"). This tells us that there is a shared overlapping region between W and K.
Step 3: Evaluate Conclusion II ("Some K are not J"). We know that some part of K sits inside the W circle. Since nothing inside the W circle can ever be J, that specific part of K can never be J. Thus, it is absolutely true that some K are not J.
Final Answer: Option B
