The sentence explains how the eyes of the flounder change position over time, as shown in option C.
The text shows us that in the early life of flounders, their eyes are positioned on opposite sides of the head. However, as it grows and reaches adult life, the flounder's body changes and one of its eyes moves, joining the other eye.
In this way, the two eyes are positioned on the same side of the head, which helps the flounder to camouflage themselves and escape from praetors.
The underlined sentence is "When flounders are born, their eyes are located on each side of the head, but as the flounder grows, one of its eyes migrates to the other side so that both eyes are on the camouflage."
