At which fret can you find the note G on the 5th (A) string?

The note G can be found at the 3rd fret of the 5th (A) string. This is because when tuning the guitar, each fret raises the pitch of the string by one half step (or semitone).

Starting from the open A string, if you move up to the 1st fret, you reach the note A# (or Bb), the 2nd fret gives you the note B, and the 3rd fret yields the note C. Continuing this pattern, you'll find that the 5th fret corresponds to the note D and the 7th fret gives you E. Therefore, the G note is positioned at the 3rd fret of the 5th string, making it the correct answer.
