Correct Answer: Both conclusions I and II follows


Solution : The possible Venn diagram for the given statement is as follows.


Let's analyse the conclusions –
Conclusion (I): No B is K – From the above diagram, it is clear that there is a relation of no between K and B. Thus, no B is K is true. So, this conclusion follows
Conclusion (II): Some T is B – From the above diagram, it is clear that some B is T as both B and T circles shared their part. Thus, this conclusion follows.
Conclusion (III): Some T are K – From the above diagram, it is clear that between T and K no relation is built. As circles of both T and K have no relation. Thus, some T are K are not true. So, this conclusion doesn't follow.

So, conclusions I and II follow. Hence, the first option is correct.
