yes you are absolutely right. This qn is basically testing your knowledge of what causing or what is Papilledema.
Papilledema is caused by too much CSF accumulate in the ventricles and optic nerve sheath. As the optic nerve sheath is continuous with the subarachnoid space of the brain (and is regarded as an extension of the central nervous system), increased intracranial pressure is transmitted through to the optic nerve. This will cause optic disc swelling.
