Final answer:
Infants can differentiate between phonemes from various languages. So, the correct answer is option c.
Step-by-step explanation:
Research on the perception of phonemes by infants reveals that infants can differentiate between phonemes from various languages. Initially, babies can discriminate among the sounds that make up different languages, but by the time they are around 1 year old, they can only discriminate among the phonemes used in the language(s) spoken in their environment (Werker & Tees, 1984).
This ability to perceive phonemes is an important part of language acquisition during early development. So, the correct answer is option c.
