Correct answer: A — Offer radiofrequency ablation in a specialist Barrett service

Option A is correct because confirmed low-grade dysplasia on two endoscopies with two-pathologist review meets the NICE threshold for radiofrequency ablation. Option B under-treats a higher-risk state. Option E is disproportionate for flat low-grade dysplasia. Option C uses resection where there is no target lesion, and option D is specifically not recommended as chemoprevention.
