C is correct because SAS Viya Text Analytics aggregates sentence-level sentiment scores to the document level by combining positive and negative sentence counts, average polarity, and sentiment strength — not simply max or first-sentence sentiment. The exact aggregation method considers the relative counts and magnitudes of positive/negative sentiment across all sentences. A is wrong; leading sentence dominance is not how SAS aggregates. B is wrong; length-weighted averaging is not the SAS sentiment aggregation approach. D is wrong; max sentiment would ignore negative sentences entirely.
