What is the note on the 1st String at the 4th Fret?

On a standard-tuned guitar, the 1st string is the thinnest string, which is tuned to E. To determine the note at the 4th fret of this string, you count up four half steps from E:

1. The 1st fret is F (one half step up from E).

2. The 2nd fret is F# (two half steps up).

3. The 3rd fret is G (three half steps up).

4. The 4th fret is G# (four half steps up).

Given that the highest note reached on the 1st string at the 4th fret, G# is not in the list of choices provided, but the note corresponding to the 1st string at the 4th fret is actually B. A is indicated mainly for the other correct options, but clearly, the answer aligns with the understanding of the guitar fretboard divisions and chromatic scale progression. Therefore, if the given answer is G, it might be better indicated as B.
