Correct answer: A — At least 4 mm

A low-risk cutaneous squamous cell carcinoma is excised with at least a 4 mm clinical peripheral margin. High-risk disease requires at least 6 mm or a margin-controlled technique depending on site and features. Combining 4–6 mm into one answer obscures the risk-stratified distinction.
