الإجابة: C. LP albuminocytological disassociation
Ascending symmetric numbness with areflexia 1–4 weeks after gastroenteritis (Campylobacter) is Guillain–Barré syndrome. The key LP finding is albuminocytologic dissociation (high CSF protein, normal cell count). GBS is post-infectious autoimmune, not nutritional; it starts distally (stocking-glove) and ascends; the diagnosis rests on CSF and nerve conduction studies, not MRI.

GBS is a post-infectious autoimmune disease (about 2/3 of cases follow a respiratory or GI infection 1-4 weeks earlier), not a nutritional problem.

B
ليش غلط
The source says GBS is diagnosed by a combination of CSF analysis, clinical findings and nerve conduction velocities; MRI is not the best diagnostic test.

C

The LP in GBS shows albuminocytologic dissociation: elevated CSF protein with a normal cell count.

This patient's numbness and sensory loss are below the knee, i.e. distal. GBS typically begins with paresthesias in the distal extremities and then ascends from the lower to the upper limbs, so 'more proximal than distal' does not describe this presentation.
