Answer 2

Step-by-step explanation:

A sharp symbol on a line or space in the key signature raises the notes on that line or space one semitone above the natural, and a flat lowers such notes one semitone. ... Each major and minor key has an associated key signature that sharpens or flattens the notes which are used in its scale.
