Correct answer: B — Benign paroxysmal positional vertigo

Brief vertigo triggered by head movement with normal neurological examination is typical of benign paroxysmal positional vertigo. Orthostatic hypotension causes light-headedness on standing, vestibular neuritis is sustained, stroke usually has focal signs, and Meniere's disease includes fluctuating hearing symptoms. The Dix-Hallpike test and repositioning manoeuvres are appropriate in a compatible presentation.
