الإجابة: B. LAMA + LABA
FEV1/FVC 0.55 with FEV1 65% is GOLD 2. Dyspnea on walking 1-2 blocks (mMRC ≥2) with no exacerbations puts him in GOLD group B, where initial therapy is LABA + LAMA. Azithromycin is only an add-on for persistent exacerbations, and as-needed ICS-formoterol is an asthma regimen.
