Correct Answer: Only conclusion I follows


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

Let's analyse the conclusions –
Conclusion I: No T is R – From the Venn diagram, it is evident that there is a negative relation between T and R. So, from this, it can be concluded that no T is R. Therefore, this conclusion follows.
Conclusion II: No H is T – From the Venn diagram, it is evident that some parts of the circle representing H lie inside the circle representing T while some lie outside. So, from this, it can be concluded that some H is T. Therefore, this conclusion doesn't follow.
Conclusion III: No R is H – From the Venn diagram, it is evident that there is no direct relation between R and H. So, no definite relation can be drawn. Therefore, this conclusion doesn't follow.

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