Concept:Possibility-based conclusion in syllogism: a conclusion is true if it does not contradict the given statements, even without a definite relation.
Explanation:The given statements are: All bike are wheels; No road is a bike; All road is a track.
There is no direct relation between road and wheels.
However, no road being a bike does not stop some road from being wheels, because wheels can exist outside the bike set.
So, the possibility that some road are wheels is valid.
Thus, Conclusion I is true.
For Conclusion II, "Only a few bikes is a track" means some bikes are track and some bikes are not track.
But there is no definite relation given between bikes and tracks.
Therefore, we cannot conclude this.
So, Conclusion II is false.
Answer:Only I follows.
Hence, the correct option is C.
