Correct Answer: All of the conclusions follow
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): No house is a classroom – Because there is a negative relation between school and park and the classroom is completely inside the school and the house is completely inside the park. Therefore, no house is a classroom is also true. Conclusion (II): No park is a classroom – Because there is a negative relation between school and park and the classroom is completely inside the school. Therefore, no park is a classroom is also true. Conclusion (III): No school is a house – Because there is a negative relation between school and the park and the house is completely inside the park. Therefore, no school is a house is also true.
So, all of the conclusions follow. Hence, the first option is correct.
