Answer:
A. a minor
Step-by-step explanation:
- Each major scale, has its relative minor scale.
- The C major scale is CDEFGAHC and its relative minor starts from the sixth tone of that scale, hence AHCDEFGA.
- Due to the difference in the intervals between the tones in the major and the minor, although the tones are quite the same, the major scale sounds 'cheerful' and the minor 'sad' '.
