الإجابة: A. Blunting of the costophrenic angle, homogeneous opacity, meniscus sign
Stony dullness, reduced fremitus and reduced expansion (in a breast cancer patient → likely malignant effusion) point to pleural effusion. On CXR, effusion shows blunting of the costophrenic angle and a homogeneous opacity with a meniscus-shaped margin. Option B describes COPD/hyperinflation, C describes heart failure, and D (hyperlucent hemithorax, absent markings) describes pneumothorax.

Hyperinflation with a pushed-down, flattened diaphragm is the CXR picture of COPD, not of an effusion.

Cardiomegaly, pulmonary congestion and Kerley B lines are the CXR findings listed for heart failure, not the sign of the effusion itself.

Absent lung markings on the affected side with a pleural line detached from the chest wall is the pneumothorax pattern, not an effusion.
