A) Arcuate fasciculus runs between the frontal lobe and superior parts of the parietal and occipital lobes.

B) Arcuate fasciculus runs adjacent to the superior occipitofrontal fasciculus and is a bundle of fibers on their way to the caudate nucleus.

C) Arcuate fasciculus is a connection between the frontal lobe and posterior portions of the hemisphere, and fans out among the parietal, occipital, and temporal lobes.

D) The arcuate fasiculus hooks around the margin of the lateral sulcus to interconnect the orbital cortex and anterior temporal cortex.
