Correct option is D
From the given information following Venn diagram will be drawn-

Conclusion I: All R are C.
· This conclusion directly follows from Statement II, which states that "All R are C." Conclusion I follows.
Conclusion II: Some R are A.
· This conclusion also follows because Statement I states "All A are R," which implies that there is an overlap between R and A. Hence, some R are indeed A. Conclusion II follows.
Conclusion III: No C is R.
· This conclusion does not follow because Statement II clearly states "All R are C." This implies there is a relationship between C and R, and we cannot conclude that no C is R. In fact, all R are part of C, which directly contradicts this conclusion. Conclusion III does not follow.
The correct answer is that only Conclusions I and II follow.
Answer: (d) Only Conclusions I and II follow.
