Correct answer: C
The statement "All Plants are Carnivorous" is a Universal Affirmative (A-type) proposition. In categorical logic, if an A-type statement is false, its contradictory O-type statement must be true. The logical contradiction of "All S are P" is "Some S are not P". Therefore, if the given statement is false, it implies that "Some plants are not carnivorous" must be true. This matches option D.
