Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 1 i.e. Only conclusions II and III follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. All cats are plants → False (It is possible, but no definite conclusion can be drawn).
II. Some plants are cats → True (As all animals are plants and some cats are animals, we can conclude that some plants are cats.)
III. Some plants are animals → True (As all animals are plants, so some plants are animals is true.)
IV. All animals are cats → False (It is possible, but no definite conclusion can be drawn).
Hence, Only conclusions II and III follow.
