Step 1: Analyze Conclusion I:
- Some cats are ants (from Statement II).
- All ants are black (from Statement I).
- Since some cats are ants and all ants are black, some cats must be black.
Conclusion I is correct.
Step 2: Analyze Conclusion II:
- From Statement I, we know all ants are black, meaning all ants belong to the black category.
- Statement II says some cats are ants, meaning some cats are also black.
- This implies that some blacks are cats.
Conclusion II is also correct.
Step 3: Since both conclusions are valid, the correct answer is Both conclusions I and II follow.
