E
A or VI or 6
The 4th through sixth (or Subdominant through Submediant) are major, which means 2. The roman numerals are iv and VI.
G
A G major triad consists of three notes: G, B, and D. The G note is the root, B is the major third, and D is the perfect fifth. Together, these notes create the harmonious sound characteristic of a G major chord.
A G major triad consists of three notes: G, B, and D. The root note is G, the major third is B, and the perfect fifth is D. Together, these notes create the harmonious sound characteristic of the G major chord.
The submediant, the sixth degree of the G major scale, is E.E natural
B major's submediant note is g#
G Major
The submediant of E major is C♯ minor. In the context of a major scale, the submediant is the sixth degree, and in the E major scale (E, F♯, G♯, A, B, C♯, D♯), the sixth note is C♯. Thus, C♯ minor serves as the submediant chord in the key of E major.

C Major chord = C E G
The minor scale that has B flat as its submediant is the D minor scale. In the D minor scale, the notes are D, E, F, G, A, B flat, and C, making B flat the sixth note, or submediant, of the scale.
The submediant - which is the note a relative minor scale begins on
The tonic, the submediant and the dominant (1, 3 and 5).
The chords BVI, BVII, and I in a major key are related as the submediant, subtonic, and tonic chords respectively. They create a sense of resolution and stability in the key, with the submediant and subtonic chords leading to the tonic chord.
In the perspective of European-descendent theory, the degrees of any key or scale (major, minor, or modal) can be classified as follows: 1 - Tonic 2 - Supertonic 3 - Mediant 4 - Subdominant 5 - Dominant 6 - Submediant 7 - Leading Tone Let us take the case of C major as our key/scale: C - Tonic D - Supertonic E - Mediant F - Subdominant G - Dominant A - Submediant B - Leading Tone Similarily, this works in the minor keys, too. Using A natural harmonic as our key/scale: A - Tonic B - Supertonic C - Mediant D - Subdominant E - Dominant F - Submediant G - Leading Tone
