The correct answer is C major because the given key signature has no sharps or flats, indicating that it is in the key of C major. In the key of C major, the notes used are C, D, E, F, G, A, and B, with no accidentals.

The key of Bb major is the correct answer because it has two flats in its key signature, Bb and Eb. This can be determined by looking at the order of flats in the circle of fifths. Additionally, the key of Bb major is commonly used in music and has a distinct sound and feel.

The key of F major is determined by the presence of one flat in its key signature, which is Bb. In this question, the key signature is not explicitly given, but the answer "F major" suggests that there is one flat present. The other options, Bb major, A major, Ab major, and D major, all have different key signatures, indicating that they are not the correct answer. Therefore, F major is the most fitting choice based on the information provided.

The key of a piece of music refers to the tonal center or the main note that the piece revolves around. In this case, the key signature of the given question is not provided, so we need to determine the key based on the notes provided. By looking at the notes, we can see that the key signature contains three sharps: F#, C#, and G#. The only option that matches this key signature is A major, which has those three sharps in its key signature. Therefore, the correct answer is A major.

The key of D major is the correct answer because it is the only key in the given options that contains the note D as its tonic. In the key of D major, the notes D, E, F#, G, A, B, and C# are used, and the key signature consists of two sharps, F# and C#. Therefore, based on the information given, D major is the most fitting answer.

The key of a piece of music refers to the tonal center or the main note or chord that the piece revolves around. In this case, the correct answer is E major.

The other options (B major, D major, A major, and G major) are not the correct answer as they do not match the given key signature.

The key signature of Ab major consists of four flats: Bb, Eb, Ab, and Db. In the given options, Ab major is the only key that includes all four flats. Therefore, Ab major is the correct answer.

The correct answer is Eb major. This is determined by the key signature, which consists of three flats: Bb, Eb, and Ab. The presence of these flats indicates that the key is Eb major.
