Q.

statements:
All flowers are trees. No fruit is tree.
Conclusions:
I.No fruit is flower.
II.Some trees are flowers.
                        
A. Only conclusion I follows B. Only conclusion II follows
C. Either I or II follows D. Neither I nor II follows

Answer: Option E
Explaination:

 


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.
