What Is the Impact of Experience on Categorical Perception

What is the impact of experience on categorical perception?

A) Categorical perception is not present in young infants and appears to be entirely dependent upon experience.
B) Infants possess an innate ability to discriminate a wide range of sound contrasts, but the environment quickly begins to fine-tune the discriminations, eliminating those that will not be needed and improving the child's ability to use others.
C) Categorical perception is present in newborns, and while infants never lose the ability to discriminate phonemic boundaries, they become more skilled at detecting subtle differences between categories based on their experience of hearing a language being spoken.
D) Categorical perception is present in newborns and is not modifiable by experience.
