Correct answer is A.
(A) Pseudotumor cerebri, or benign intracranial
hypertension, is characterized by increased
intracranial pressure, normal or small
ventricles, and normal cerebrospinal fluid.
Symptoms include headache, irritability, nausea,
disturbances of visual acuity, dizziness,
and tinnitus. Often, it is a manifestation of hypervitaminosis
A. Although it is thought of as
benign, progressive visual field and acuity
loss may occur. (Oski et al, pp 594, 897)
