This question tests the classical clinical association of four chest examination signs.
- Localized wheeze: A wheeze confined to one area suggests a local airway narrowing, classically from a bronchial tumour.
- Shifting dullness: A dullness level on percussion that shifts with position change happens when air and fluid coexist in the pleural space, as in hydropneumothorax.
- Ellis curve: This curved line of dullness, higher in the axilla, is the classic sign of a pleural effusion.
- Intercostal tenderness: Tenderness over the intercostal spaces from underlying pus points to an empyema.
Putting these together gives A-4, B-3, C-1, D-2.
Let's summarize:
- Each chest sign here has one specific classical disease association.
- Localized wheeze-tumour, shifting dullness-hydropneumothorax, Ellis curve-effusion, intercostal tenderness-empyema.
So the correct match is A-4, B-3, C-1, D-2.
