Concept:Syllogism uses statements to deduce valid conclusions.Explanation:• Statement 1: Some phones are watches. So there is an overlap between phones and watches.• Statement 2: All watches are guns. So the entire set of watches is inside guns.• Thus, the overlapping phones (that are watches) are also guns. So some guns are phones. Conclusion II is valid.• Conclusion I says "All guns are watches". This is the converse of statement 2, which is not necessarily true. So it does not follow.Answer:Only conclusion II follows. So the correct option is B.
