A)Lesions to the right striate cortex AND the left inferior temporal lobe
B)Lesions to the right striate cortex AND the corpus callosum
C)Lesions to the right striate cortex AND the corpus callosum AND the left inferior temporal lobe
D)Lesions to the right striate cortex AND the corpus callosum AND the right inferior temporal lobe

The question is asking about the minimal lesions required to produce an object recognition deficit in the "what" pathway, which involves bilateral inputs from the primary visual cortex. Lesions to one hemisphere alone would not be sufficient, so options A and B can be ruled out. Lesions to both the right striate cortex and the corpus callosum would disrupt communication between the two hemispheres, but would not necessarily affect object recognition in the "what" pathway specifically. Therefore, the minimal lesions required would be those that affect both the right striate cortex and the left inferior temporal lobe, which are both involved in the "what" pathway. Option C is the only choice that includes both of these regions. Lesions to the right inferior temporal lobe would not be necessary to produce an object recognition deficit, as the left hemisphere is primarily responsible for processing the right visual field, and the right inferior temporal lobe is primarily involved in processing the left visual field.
