The primate has been trained to respond to visual stimuli and is tested with a purple stimulus in the lower left quadrant. Given the lesion's location, the primate's ability to accurately reach for targets in the lower left quadrant suggests it may exhibit blindsight, which is the ability to respond to visual stimuli without conscious visual perception. Therefore, the correct answer is that the primate demonstrates blindsight for stimuli in the lower left quadrant."}
