Which statement best describes an embolic stroke?

An embolic stroke occurs when an embolus travels through the bloodstream from a distant site and suddenly lodges in a cerebral artery, blocking blood flow and causing abrupt brain ischemia. The statement describing a mass traveling to a cerebral artery from a remote site captures that mechanism precisely. The other scenarios describe different processes: a brain bleed is a hemorrhagic stroke, not an embolic blockage; a stroke caused by local atherosclerotic narrowing progresses due to in-situ thrombosis rather than distant travel; and reduced cerebral perfusion from systemic hypotension leads to hypoperfusion injuries rather than an occluding traveling object.
