Statements: All flowers are trees. No fruit is tree.
Conclusions:
- No fruit is flower.
- Some trees are flowers.
Answer: Option
Explanation:
As discussed above, the conclusion must be universal negative and should not contain the middle term. So, it follows that 'No flower is fruit'. I is the converse of this conclusion and thus it follows. II is the converse of the first premise and so it also holds.

Both are universal and conclusion II is particular. Also it contains middle term and as statement contains negative the conclusion should be negative. So a is the answer I think.
