To determine which example spells the word "decade," you would need to analyze the musical notes in each example. Unfortunately, I do not have visual access to the musical notation shown in the examples.
If you would like help identifying the notes or the corresponding letters they represent (D, E, C, A, D, E) in musical notation, you'd need to describe the notes to me, or I can guide you on how to identify them based on their position on the staff.
If you can provide the notes or their positions on the staff, I’d be happy to help you determine which example spells "decade!"
