Question

in the babbling stage, what do infants do? make spontaneous consonant - vowel pairs by bunching tongue reflect the work of the parents to teach them sounds. imitate primitive adult language sounds heard from adults speak distinctive language sounds from various cultures

Explanation:

In the babbling stage, infants spontaneously produce consonant - vowel pairs (like "ba - ba", "da - da") often by movements of the tongue (bunching etc.). Parents don't "teach" sounds in a direct instructional way at this stage, infants don't imitate adult - like primitive sounds (imitation comes later), and they don't produce sounds from various cultures as they are just starting to vocalize with basic sound combinations. So the correct description is "make spontaneous consonant - vowel pairs by bunching tongue".

Answer:

Option: make spontaneous consonant - vowel pairs by bunching tongue
