The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. All enzymes are carbohydrates → True (As all enzymes are vitamins, and all vitamins are carbohydrates, so, all enzymes are carbohydrates is also true.)
II. No enzyme is a carbohydrate → False (It is possible but no definite conclusion can be drawn.)
Hence, Only conclusion I follows.
