Solution

The correct option is A trachea
  • The inhaled air first enters the nostril and then goes into the nasal cavity.
  • The air then passes through the pharynx and reaches the lungs through the trachea which is a long pipe-like structure also known as windpipe.
  • The diaphragm is a dome-shaped structure that facilitates breathing.
