The correct answer is B. Depth perception
Step-by-step explanation:
Depth perception refers to the ability to understand the world and all objects in it have three dimensions; this implies to recognize how long, high, and deep an object is. In the case of babies, especially newborns, they lack depth perception because they do not understand objects have three dimensions, and due to this, they do not have a perception of different heigh on a surface which makes them not recognize if they can fall. This occurs because newborn brains and eyes need to develop. Thus, the type of perception newborn baby is lacking is "depth perception" that begins to be developed when babies are around 6 months old.
