since noone else is jumping on this, i suppose i will.

c major and a minor have the same notes, but that doesnt make them the same scale. the root is different. one is major the other minor.

A min is the relative minor of C.

I was keeping my mouth shut.
You are rigth, the fact that they have the same notes does not make them the same scale, they are just relatives.
The major scale has a different root, tonality, step pattern, intervallic structure and its own cadences.



On another note:

The only diatonic scale that would fit this progression is A minor or C major.

Those are not the ONLY scales compatible with those chords:
Just to name a few:
E Neopolitan minor
A Ethiopian Geez & Ezel
G Dominant 7th Scale, etc.
