Concept:Syllogism: Distinguishing definite conclusions from possibility statements.
Explanation:“Only a few Mobile are Charger” means some Mobile are Charger and some Mobile are not Charger.
All Charger are Black.
“Only a few Black are White” means some Black are White and some Black are not White.
From the first two statements: Some Mobile are Charger and all those Charger are Black, so some Mobile are definitely Black.
Conclusion I: “Some White being Charger is a possibility.”
There is no negative link between White and Charger, so it can be possible. This follows.
Conclusion II: “Some Mobile being Black is a possibility.”
But some Mobile are already Black definitely, so a possibility statement about a definite fact is false. This does not follow.
Conclusion III: “Some Black are not White is a possibility.”
From “only a few Black are White” we know some Black are not White is a definite fact. A possibility about something already definite is false. This does not follow.
Thus only Conclusion I follows.
Answer:Only Conclusion I follows (Option A).
