To arrive at this answer, we examine the notation provided and look at the highlighted chords. We observe that all of the highlighted chords have a C note in them. This is evident from looking at the notes listed for each chord: middle C, E, G in Chord 1, F, A, C in Chord 4, G, B, D in Chord 5, and C (space 3), E (space 4), G (sitting on top of staff) in Chord 8. Therefore, we can conclude that what the highlighted chords have in common is the presence of a C note.
