Step-by-step solution
Venn Diagram Method: Conclusions: I. Some orbit are planet II. Some planet are moon. Checking Conclusion I: Some orbit are planet Clearly we can see from the venn daigram that no orbit is planet. Hence, C1 doesn't follow. Checking Conclusion II: Some planet are moon. Since All moon are planet we can say that some planet will also be moon. C2, hence, follows here. Option B is hence the correct answer.
