PICA supplies which regions?

Explanation:
The regions supplied by the posterior inferior cerebellar artery (PICA) include the posterolateral (dorsolateral) part of the medulla oblongata and the inferior surface of the cerebellum, as well as structures around the fourth ventricle, including the choroid plexus. This matches the option that lists posterior portions of the cerebellum, lateral medulla oblongata, choroid plexus, and fourth ventricle. The frontal and parietal lobes are supplied by the anterior and middle cerebral arteries, the occipital lobe by the posterior cerebral artery, and the spinal cord is not the sole or primary territory of PICA.
