The relative major of A minor is which key?

• A. A minor
• B. G major
• C. C major
• D. F major

Answer: (C)

The idea here is that a relative major shares the same set of pitches as its minor counterpart, and it sits a major third above the minor tonic. For A minor, the notes are A B C D E F G, which match C major exactly. The major key built on the note a major third above A is C, and it uses the same no-sharp, no-flat key signature. So the relative major is C major.

The other options would change the key signature: G major has one sharp, and F major has one flat, unlike A minor (and C major), so they aren’t the relative major. A minor itself is the minor key, not its relative major.
