In minor keys, an authentic cadence typically moves from which chords?

• A. V to i
• B. V to I
• C. I to V
• D. iv to V

Answer: (A)

An authentic cadence is the strongest close in a tonal system because it resolves to the tonic chord. In minor keys, the tonic is i (a minor triad). To create a firm pull to that tonic, the dominant chord is typically used in a major form (V, often with or without seventh) by raising the leading tone in the harmonic minor. This V to i motion provides a decisive sense of ending, which is exactly what an authentic cadence aims for. The other progressions don’t land on the tonic in a way that delivers that clear, final closure characteristic of an authentic cadence.
