Correct answer: B — Anterior to the heads of the ribs
The thoracic sympathetic chain lies anterior (anterolateral) to the heads of the ribs and the costovertebral joints under the parietal pleura. It runs from the stellate ganglion (C7-T1) superiorly to the diaphragm where it continues as the lumbar sympathetic chain on the anterolateral aspect of the lumbar vertebral bodies.
