Correct Answer: Neither conclusion I nor II follows


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

Let's analyse the conclusions –
Conclusion (I): All blue is black – According to the Venn diagram there is no definite relation between blue and black. Therefore, all blue are black is a false conclusion.
Conclusion (II): All pink is black – According to the Venn diagram, some pink is black. Therefore, all pink is black is a false conclusion.

So, neither conclusion I nor conclusion II follow. Hence, the second option is correct.
