Quizplus · Accepted Answer

B) "gaga" is least likely because it involves a more complex coordination of the vocal tract that is typically seen in the babbling stage, not before it. Babbling often includes repeated consonant-vowel pairs, which "gaga" represents, indicating a developmental milestone that hasn't been reached by infants who haven't started babbling yet.
