|
Conclusions:
I. Some orbit are planet
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.
