Ungerleider and Mishkin's study showed that lesions in the parietal cortex of monkeys impaired their performance on spatial tasks, such as identifying landmarks, which is why option A is correct. This study helped establish the understanding of the dorsal stream (parietal pathway) as involved in processing spatial location and the ventral stream (inferotemporal pathway) as involved in object recognition.
