Correct answer: E — 2 cm

NICE recommends a 2 cm clinical margin for stage II melanoma, which includes a 2.5 mm primary in the absence of a different staging qualifier. A stated range of 1–2 cm is too ambiguous for the UK single-best-answer context. Reconstruction planning should not compromise oncological clearance.
