Correct Answer: Both conclusions I and II follow


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

Let's analyze the conclusions –
Conclusion (I): All A are C From the Venn diagram, it is evident that the circle representing A is completely overlapped by the circle representing C. Thus, it can be concluded that all A are C.
Conclusion (II): Some R are A From the Venn diagram, it is evident that some parts of the circle representing R lie inside the circle representing A while some lie outside. Thus, it can be concluded that some R are A.
Conclusion (III): No C is R From the Venn diagram, it is evident that some parts of the circle representing C lie inside the circle representing R while some lie outside. Thus, this conclusion does not follow.
