Where are the parietal pleura and visceral pleura located?

The parietal pleura lines the inner surface of the thoracic cavity (chest wall, diaphragm, and mediastinal surfaces), while the visceral pleura directly covers the lungs. The space between them, the pleural cavity, contains fluid to allow smooth movement during breathing. So the correct description is that the parietal pleura lines the thoracic cavity and the visceral pleura covers the lungs. The other descriptions misplace the layers or refer to structures like the heart or trachea, which are not covered by pleura in that way.
