B) All Diamond is Platinum (A) + Only a few Platinum is Gold (I) → No conclusion. Hence conclusion I does not follow. Only a few Platinum is Gold (I) + Every Gold is Copper (A) → Some Platinum is Copper (I). Hence conclusion II follows. C) Only a few Platinum is Gold (I) + Every Gold is Copper (A) → Some Platinum is Copper (I) → Conversion → Some Copper is Platinum (I) + All Platinum is Silver (A) → Some Copper is Silver (I). Hence conclusion I does not follow. Only a few Platinum is Gold → All Gold can be Platinum (A). Hence conclusion II does not follow.
