Correct answer: A — No surveillance colonoscopy; return to population screening

Explanation lettering: E = shown as A · A = shown as D · D = shown as E

Correct answer is E. In UK practice, 1–2 tubular adenomas <10 mm represent a low‑risk scenario. NICE CG118 suggests that a one‑off colonoscopy at 5 years may be considered, but if negative surveillance stops—practically equivalent to returning to screening. The latest BSG/ACPGBI/PHE 2020 guidelines do not include low‑risk adenomas in surveillance criteria (high‑risk defined by advanced or multiple polyps), so these patients return to the screening programme. Option B reflects outdated guidance; A, C and D correspond to higher‑risk protocols and are incorrect.
