Correct answer: B — Restless legs syndrome

Urge to move the legs, worsening at rest and night, with relief by movement suggests restless legs syndrome. Peripheral arterial disease causes exertional claudication, Parkinson's disease has bradykinesia, nocturnal epilepsy has stereotyped events, and cervical myelopathy causes upper motor neurone signs. Iron deficiency should be considered in restless legs symptoms.
