Explanation:

Pleural metastases are common in breast and lung cancer due to their anatomical proximity and vascular/lymphatic spread patterns. Breast cancer can metastasize via lymphatics to the pleura. Lung cancer, being in the thoracic cavity, can directly invade or metastasize to the pleura. Renal cell carcinoma (B) typically metastasizes to bone, lung, liver. Prostate cancer (C) often goes to bone. Osteosarcoma (D) commonly metastasizes to lung.
