Restate the question in your own words, predict the answer before checking the options, and confirm that the explanation and correct-option field both point to Lungs (bronchi).
Therefore option C, Lungs (bronchi), is factually consistent with the stem, the marked correct index, and the explanation.✅ Correct Answer: C — Lungs (bronchi) The Trachea (windpipe) is a tube that carries air from the larynx (voice box) down to the lungs. It divides at the lower end into two primary bronchi — right bronchus and left bronchus — each leading into the respective lung. The epiglottis prevents food from entering the trachea during swallowing. Stomach — The stomach is connected to the oesophagus (food pipe), not the trachea. The trachea carries only air. Oesophagus — Oesophagus (esophagus) is the food pipe that connects the throat to the stomach; it runs parallel to the trachea but carries food. Heart — The heart is not directly connected to the trachea; blood vessels (arteries and veins) connect to the heart, not the trachea. 📝 Important Note: Trachea = windpipe; Oesophagus = food pipe. Epiglottis closes the trachea during swallowing to prevent choking. Trachea is about 10-12 cm long, has C-shaped cartilage rings. Bronchi lead to bronchioles then alveoli in lungs.
