Arachnoid granulations are located in which of the following locations?

Explanation:
Arachnoid granulations are the exit points for CSF, reabsorbing it into the venous system by protruding into the dural venous sinuses, especially the superior sagittal sinus. This location is where CSF returns to the blood after circulating in the subarachnoid space. They are not in the choroid plexus (which produces CSF) or in the ventricles themselves, and they are not in the central canal of the spinal cord. So the dural venous sinuses are the correct location.
