Correct answer
Both conclusions I and II follow
Why this answer is correct
The least possible Venn diagram is:
Conclusions:
I. Some jackals are lions → Follows (As, All rats are lions and Some rats are jackals)
II. Some rats are not mongoose → Follows (As, Some rats are jackals and No jackal is mongoose)
III. No mongoose is a lion → Does not follow (It can be possible, but it is not definite)
Hence, 'Both conclusions I and II follow' is the correct answer.
