Reveal the answer and explanation

Correct answer: C — Explain eligibility using age, pack-years and quit interval

Explanation lettering: E = shown as C · C = shown as E

E is correct: organized screening uses both age/pack-year burden and a recency-of-smoking criterion; remote quitters may fall outside eligibility. A omits the recency criterion. B and C are not screening modalities. D confuses eligibility counselling with diagnosis.
