Answer:
b. left; right
Explanation:
Left visual field: The left visual field is being present in each eye of an individual that has both the right and the left hemifields and via optic chiasm of an individual's eye the different visual signals from both eyes' left hemifields are being sent to the brains' right hemisphere whereas the eyes' right hemifields sent signals to the brain's left hemisphere.
Right visual field: The right visual field of an individual generally maps towards an individual's left hemisphere and vice-versa yet each eye of an individual tends to connect both the hemisphere in cats, humans, monkeys, etc.
