- The prefrontal cortex is a critical region of the brain located at the front part of the frontal lobes.
- Its primary role is associated with executive functions, which include complex cognitive processes such as decision-making, problem-solving, planning, and impulse control.
- These functions are essential for goal-directed behavior and adaptive responses in changing environments.

- In contrast, sensory processing primarily occurs in the primary sensory cortices located in the parietal, temporal, and occipital lobes.
- Visual perception is mainly handled by the occipital lobe, especially the primary visual cortex.
- Motor coordination is primarily the function of the cerebellum and the motor cortex in the frontal lobe, but not specifically the prefrontal cortex.

Therefore, the correct answer is Executive functions because the prefrontal cortex is key in managing high-level cognitive tasks rather than basic sensory or motor functions.
