Correct answer: C — Focal cerebral arteriopathy (post-infectious)

Focal cerebral arteriopathy (FCA) is the most common cause of arterial ischaemic stroke in previously healthy children. It typically involves the distal ICA or proximal MCA, often following a viral infection (especially varicella). It may be monophasic or progressive. Management includes aspirin and close neurovascular surveillance.
