Correct answer: C — He does not yet meet the Australian program’s 30 pack-year criterion

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

E is correct. The live Australian program requires at least 30 pack-years in addition to age, symptom and smoking/quit-time criteria; family history does not substitute for the threshold. A and B apply criteria the program does not use. C and D are ineffective screening substitutes. Clinical assessment remains appropriate if symptoms develop.
