Final answer:
The correct option in the final answer is c. Visual agnosia is linked to damage in the 'what' system of visual processing, which involves the ventral stream from the occipital cortex to the temporal cortex, responsible for identifying visual stimuli.
Step-by-step explanation:
Visual agnosia is associated with damage to the brain area that processes complex visual information and is responsible for identifying visual stimuli and their significance. This area is part of the ventral stream, which takes visual information from the primary visual cortex and sends it to structures within the temporal lobe, where it begins to interact with non-visual cortical areas that may be significant in forming visual memories.
Thus, visual agnosia, which is a disorder characterized by an inability to recognize familiar objects or faces despite having the ability to see them, is linked to dysfunction in these temporal lobe structures.
The correct answer to the student's question is (c) the "what" system, which carries information from the occipital cortex to the temporal cortex.
