Step 1: Identify the function of the occipital lobe.
The occipital lobe, located at the back of the brain, is primarily responsible for processing visual information.
Step 2: Understand the role of different lobes.
The frontal lobe is responsible for speech and decision-making.
The temporal lobe is responsible for hearing and memory. The occipital lobe is specialized for vision.
Step 3: Analyze the options.
Speech is controlled by the frontal lobe, not the occipital lobe.
Hearing is controlled by the temporal lobe.
Memory is stored in the hippocampus, part of the temporal lobe. Vision is directly linked to the occipital lobe, so damage here would result in vision loss. Conclusion: If the occipital lobe is damaged, vision is lost, so the correct answer is (C) Vision.
