Explanation:

In infant development, a baby's vision typically reaches a complete (more mature, like adult - like in many aspects) level around 8 months to a year. At this stage, their visual perception, including depth perception, color vision, and ability to track objects, has developed significantly. The other age ranges (1 - 2 months, 3 - 4 months, 5 - 6 months) are earlier stages of visual development where the baby's vision is still maturing but not at the complete level.

Answer:

8 months to a year
