Answer:
Without knowing which three chords are being referred to, it is difficult to provide a specific answer. However, based on the answer choices provided, the most likely correct answer is "the same shape."
Chords in music are created by playing two or more notes simultaneously. Chords can have different qualities, names, and uses depending on the notes used and the context in which they are played. However, chords with the same shape have the same finger placement on the instrument, regardless of their name or quality.
For example, a major chord and a minor chord can have different names and qualities, but if they have the same shape, they will be played using the same finger placement on the instrument. Similarly, power chords are a type of chord that typically have a simple two-note structure and a specific shape that is used frequently in rock and metal music.
So, in general, chords with the same shape will have the same finger placement on the instrument, even if they have different names or qualities.
