Correct Answer: Only conclusions I and III follow


Solution : The possible Venn diagram according to the given statements is as follows –

Let's analyse the conclusions –
Conclusion (I): Some students are teachers – From the Venn diagram, the circle of the teacher is completely inside the circle of the student. Therefore, this conclusion is true.
Conclusion (II): No student is a doctor – From the Venn diagram, there is no negative relation between student and doctor. Therefore, this conclusion is false.
Conclusion (III): Some students are principals – From the Venn diagram, the circle of principals is completely inside the circle of students. Therefore, this conclusion is true.

So, only conclusions I and III follow. Hence, the fourth option is correct.
