Correct Answer: Only conclusion III follows
Solution : The possible Venn diagram, according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): All pens are phones – From the Venn diagram, it is evident that the circles representing pens and phones overlap each other and have a part of their areas in common. So, from this, it can be concluded that some pens are phones. Thus, this conclusion does not follow. Conclusion (II): All laptops are pens – From the Venn diagram, it is evident that the circles representing pens and laptops overlap each other and have a part of their areas in common. So, from this, it can be concluded that some laptops are pens. Thus, this conclusion does not follow. Conclusion (III): All pen drives are laptops – From the Venn diagram, it is evident that the circle representing pen drives is completely overlapped by the circle representing laptops. So, from this, it can be concluded that all pen drives are laptops. Thus, this conclusion follows.
So, the only conclusion III follows. Hence, the first option is correct.
