A woman is rushed to the Emergency Department following a severe motor vehicle accident. The patient is clearly in respiratory distress, and exhibits rapid, shallowing breathing that relies on accessory breathing muscles of her neck. Further examination and testing show that she has suffered an injury to her spinal cord, and her diaphragm muscle is paralyzed. Which one of the following is the most likely level of her spinal injury?
