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