Correct option is B
Given:
All fruits are apples.
Some apples are tomatoes.
No apple is a guava.
Conclusion (I): No tomato is a guava.
Conclusion (II): Some fruits are tomatoes.

From the given information seating arrangement will be.
Conclusion (I): We know no apple is a guava. While no fruit can be a guava (since all fruits are apples), tomatoes only overlap with apples. There is no statement restricting the relationship between the "non-apple" part of tomatoes and guavas. Therefore, "No tomato is a guava" is not definitely true.
Conclusion (II): All fruits are inside the apple circle, and some apples are tomatoes. However, there is no definite requirement for the tomato circle to overlap with the fruit circle. It is a possibility, but not a certain conclusion.
Neither Conclusion (I) nor Conclusion (II) follows.
Thus, correct option is (Neither conclusion I nor II follows).
