    D Only Conclusion I and II follow Correct Answer Incorrect Answer
    E All Conclusions I, II, and III follow Correct Answer Incorrect Answer

Only a few Computer are Monitor (I) + No Monitor is a Scanner (E) → Some Computer are not Scanner (O) → Probable conclusion → All Computer can never be Scanner. Hence conclusion II follows. Only a few Computer are Monitor (I) + No Monitor is a Scanner (E) → Some Computer are not Scanner (O) + Only a few Scanner is Printer (I) → Probable conclusion → Some Printer can be Computer (I). Hence conclusion III follows.
