Final Answer :
D
Explanation :
The fact that Steven was born with cataracts and his vision was so bad as a child suggests a critical period for vision development, during which his visual system did not receive sufficient input to develop normally. Although the surgical procedure allowed for some improvement, the fact that he will never achieve normal vision indicates that this critical period has passed and his visual system is permanently altered.
