Show answer & explanation
Correct answer: C
1. Analyze Statements: "All B are S" (B is entirely inside S); "No S are K" (S and K are separate).
2. Evaluate Conclusion I ("All S are B"): Invalid; the whole of S is not B, only the B part is S.
3. Evaluate Conclusion II ("Some S are B"): Valid; since all B are S, the portion of S that contains B is indeed S.
4. Evaluate Conclusion III ("All K are B"): Invalid; K is outside S, and since B is inside S, there is no relation between K and B.
Final Answer: Option C
