Step 1: Analyzing Conclusion I
- The statement is a promotional slogan, but it does not suggest that catchy slogans do not attract people.
- So, Conclusion I does not follow.
Step 2: Analyzing Conclusion II
- The statement promotes colours but does not mention water colours.
- So, Conclusion II does not follow.
Step 3: Final answer
- Since neither conclusion logically follows from the statement, the correct answer is Neither I nor II follows.
