In Brazilian Portuguese (BP) phonology, the neutralization of unstressed post-tonic final oral vowels /e, o/ into high vowels [i, u] (e.g., 'leite' -> [ˈlej.tʃi], 'bolo' -> [ˈbo.lu]) represents a widespread phonological process. Which concept best characterizes this systematic reduction of vocalic contrasts in unstressed positions?

Vowel archiphoneme realization driven by neutralization in positions of lower prosodic prominence and reduced acoustic duration. Complete phonemic split creating distinct minimal pairs exclusively in unstressed final open syllables across regional dialects. Compensatory lengthening of preceding tonic vowels caused by the complete deletion of codas in standard formal registers. Consonantal assimilation where coronals systematically delete subsequent unstressed vowels in conversational registers.

Correct Answer:

Vowel archiphoneme realization driven by neutralization in positions of lower prosodic prominence and reduced acoustic duration.
