Correct Answer: Only I and II
Solution : The Venn diagram is as follows –
Let's analyse the conclusions – Conclusion (I): No white is a pen – From the given statements, it is evident that no pen is white. So, from this, it can be concluded that no white is a pen. Thus, this conclusion follows. Conclusion (II): No red is white – From the given statements, all red are pens and no pen is white. So, from this, it can be concluded that no red is white. Thus, this conclusion follows. Conclusion (III): All pens are red – From the Venn diagram, it is evident that some part of the circle that represents pens is outside the circle that represents red. So, from this, it can be concluded that some pens are red. Thus, this conclusion does not follow.
So, only conclusions I and II follow. Hence, the second option is correct.
