Which statement is true about C Major?

• A. It has two flats
• B. It has one sharp
• C. It has no sharps or flats
• D. It has one flat

Answer: (C)

In C major, the key signature has no sharps or flats, so every note in the scale is a natural letter. The C major scale itself uses the notes C D E F G A B C, all without accidentals. That absence of sharps or flats is what makes the statement true.

If there were two flats, you’d be in a key like B♭ major (or its relative minor G minor), which includes B♭ and E♭. If there were one sharp, you’d be in G major (or E minor), with F#. If there were one flat, you’d be in F major (or D minor), with B♭. These situations show why C major uniquely has no sharps or flats.
