Correct Answer: Only conclusion I follows


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

Let's analyse the conclusions:
Conclusion (I): Some W is not X – As shown in the diagram, the arrow with a cross sign in between the circles of  X and W shows that no X is W or vice versa. If no W is X some W are not X is also true. So, this conclusion follows.
Conclusion (II): No W is R –  As shown in the diagram, the circles of R and W are independent. The diagram doesn't define any relation between them. So, this conclusion doesn't follow.

So, only the conclusion I follows. Hence, the third option is correct.
