Final answer:
Infants are born with poor visual acuity around 20/400, which improves over the first few months, approaching adult vision around six months of age, with increasing ability to perceive depth and color.
Step-by-step explanation:
The correct statement regarding the visual acuity of infants is: a. Infants are born with relatively poor visual acuity, around 20/400, and it improves gradually over the first few months of life. Newborns have the ability to focus primarily on objects that are about 46 cm (18 inches) away, which is optimal for seeing their mother's face while breastfeeding. Over time, infants start to discern colors more clearly and develop depth perception as they become more mobile. By around six months, an infant's vision has improved significantly, nearing the acuity of adult vision, and they begin to show depth discrimination.
