Correct: B — intraplaque haemorrhage. The vulnerable plaque has a large lipid core, a thin fibrous cap, macrophage infiltration, neovascularisation and intraplaque haemorrhage, and appears echolucent on duplex. Calcified, hyperechoic plaque is a marker of stability (options A and D), and the degree of stenosis is a separate axis of risk from plaque composition (option C) — a critical stenosis may be entirely stable.
