The correct answer is option 2 i.e. Only conclusions I and III follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some black are spoons. → True (As spoons are black so, some black are spoon)
II. All crows are black.→ False (It is possible, but no definite conclusion can be drawn)
III. No plate is a crow. → True (As no crow is plate)
Hence, only conclusion I and III follow is the correct answer.
