Correct answer
Only conclusion II follows.
Why this answer is correct
The least possible Venn diagram for the given statements is as below:
Conclusions:
1. Some train are stones → False (As there is no direct relation between stones and train given, it is possible but not definite). 2. Some cars are stones → True (As all the stones are rivers and all the rivers are cars thus we can say some cars will also be stones is a definite conclusion). 3. Some trains are rivers → False (As there is no direct relation between trains and river given, it is possible but not definite).
Hence, the correct answer is "Only conclusion II follows".
