Without the ability to see the image, I can guide you on how to analyze the highlighted chords. If the highlighted chords share a common note, such as all containing a C or a D, that would be their commonality. Alternatively, if they are characterized by a specific quality, like being all major or all minor, that might also be the common trait.
To answer your question accurately:
- Check if all highlighted chords are major or minor (if they are all the same type).
- Look for a common note in all the chords (C or D).
Choose the option that matches your findings. If you need help interpreting what the common feature might be based on musical theory, feel free to ask!
