Answer 1

No motorbike is a cycle. (Option B)

• According to the question, there does not exist any watch which is a cycle, and there is no cycle that is a motorbike. However, there is one type of auto, which is a motorcycle. These two shares some similarities.

• Following the hints in the question, we may conclude that "No motorbike is a cycle" because a motorbike has nothing in common with an auto, and auto has nothing in common with a cycle.

• As a result of the above, we might deduce that "no motorcycle is a cycle."

I.  No Motorbike is watch -

This can not be concluded as no direct relation given between watch and Motor bike
