Quizplus · Accepted Answer

The drawing depicts the left hemisphere of the cerebral cortex, with four different areas labeled. Based on their locations and functions, these areas are most likely the primary motor cortex (1), somatosensory cortex (2), primary visual cortex (3), and primary auditory cortex (4). These are all areas involved in processing sensory information or controlling movement, which are commonly associated with the cerebral cortex. Therefore, choice B correctly labels the drawing with these functional areas. Choices A, C, and D either incorrectly label the areas or include irrelevant structures.
