We need to check which conclusions follow.
- Step 1: Analyze statements:
- Some books are novels (Some B are N).
- All novels are stories (All N are S).
- Step 2: Use Venn diagrams:
- Some B overlap with N.
- N is a subset of S.
- Step 3: Conclusion I: "Some stories are novels." Since all N are S, some S are N (the novels). I follows.
- Step 4: Conclusion II: "Some books are stories." Since some B are N and all N are S, some B are S. II follows.
- Step 5: Options: Both I and II follow.
Thus, the answer is c.
