Solution
The correct options are
A Lungs
B Heart
In humans, the lungs and heart are situated in the thoracic chamber, which is anatomically an air-tight chamber. Thoracic chamber has a separate pulmonary cavity for housing lungs and a cardiac cavity for housing heart. The thoracic chamber is formed dorsally by the vertebral column, ventrally by the sternum, laterally by the ribs and on the lower side by the dome-shaped diaphragm. The anatomical setup of lungs in a thorax is such that any change in the volume of the thoracic cavity will be reflected in the lung (pulmonary) cavity.So, the correct answer is option B.
