Major air passages of the lungs that diverge from the windpipe.

• A. Alveoli
• B. Bronchi
• C. Bronchioles
• D. Larynx

Answer: (B)

The main idea here is the sequence of the airway branches starting from the windpipe. After air passes into the trachea, the first major passages it encounters are the bronchi, which split from the trachea to carry air into each lung. These bronchi are the primary conduits before the airway becomes smaller and branches further. Alveoli are the tiny air sacs where gas exchange happens, not passages. Bronchioles are the smaller tubes that come after the bronchi, leading toward the alveoli. The larynx sits above the trachea and serves as the voice box rather than a main branch from the windpipe. So the bronchi are the major air passages that diverge from the windpipe.
