Which lobe is most closely associated with visual processing?
- A. frontal
- B. temporal
- C. parietal
- D. occipital
Correct Answer: D
Rationale: The occipital lobe is the primary area of the brain responsible for visual processing. It contains the visual cortex, which processes information from the eyes and interprets it as images. Damage to the occipital lobe can result in visual impairments, such as blindness or difficulty recognizing objects. The occipital lobe works in conjunction with other brain regions to integrate visual information with other sensory inputs.
