Correct Answer: Only conclusions II and III follow


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

Let's analyse the conclusions –
Conclusion (I): Some tigers are not deer – According to the Venn diagram, there is no negative relation between tigers and deer. Therefore, some tigers are not deer is a false conclusion.
Conclusion (II): Some deer are wolves – According to the Venn diagram, some wolves are deer. Therefore, some deer are wolves is also a true conclusion.
Conclusion (III): Some tigers are snakes – According to the Venn diagram all deer are tigers and some deer are snakes, therefore some tigers are snakes is also a true conclusion.

So, only conclusions II and III follow. Hence, the second option is correct.
