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 rings can never be nails – According to the Venn diagram, the circles representing rings and nails overlap and have a part of their area in common which means some rings are nails. Therefore, all rings can never be nails is a false conclusion. Conclusion (II): Some beards are rings – According to the Venn diagram, there is no definite relation between beards and rings. Therefore, some beards are rings is a false conclusion. Conclusion (III): Some nails are pendants – According to the Venn diagram, the circles representing nails and pendants overlap and have a part of their area in common which means some nails are pendants. Therefore, some nails are pendants is a true conclusion.
So, only conclusion III follows. Hence, the second option is correct.
