Question 4

Some animals, like humans, have two eyes on the front of the head that perceive a mostly overlapping visual field. In contrast, some herbivores (rabbits, for example) have eyes on the sides of their head and visual fields that may not overlap at all.

A) Humans have poorer depth perception and a wider field of vision than rabbits. 
B) Humans have poorer depth perception and a narrower field of vision than rabbits. 
C) Due to integration by the brain, there is no real difference in depth perception or visual field size in humans and rabbits. 
D) Humans have better depth perception and a narrower field of vision than rabbits.
