Correct Answer: No conclusion follows


Solution : The Venn diagram is as follows –

Let's analyse the conclusions –
Conclusion I: No plate is a pencil – From the above Venn diagram, it is evident that there is no direct relation between the plate and the pencil. So, no definite relation can be drawn between them. Therefore, this conclusion does not follow.

Conclusion II: Some plates are pencils – From the above Venn diagram, it is evident that there is no direct relation between the plate and the pencil. So, no definite relation can be drawn between them. Therefore, this conclusion does not follow.
Conclusion III: Some pencils are cups – From the above Venn diagram, it is evident that there is a direct negative relation between pencils and cups. So, no positive relation can be drawn. Therefore, this conclusion does not follow.

Thus, none of the conclusions follows. Hence, the fourth option is correct.
