    D)  pleural membrane

    Correct Answer: D

    Solution :

    Lungs are enclosed in pleural membrane, which consists of two layers : the visceral and parietal. [a]The visceral pleura firmly attached to the lung itself, completely covering its surfaces except at the hilum. [b] The parietal pleura lines the interior of the chest wall and upper surface of the diaphragm. Pericardium is a two layered sac consisting of outer parietal pericardium and inner visceral pericardium attached to the heart. The pericardium protects the heart from shocks and mechanical injuries and also allows free movement of the heart. Perichondrium is the membrane of fibrous connective tissue covering the surface of cartilages except at the joints. Peritonium is the serous membrane lining the abdominal cavity and investing its viscera.
