There can be confusion between two options:
Placement of the central line via left internal jugular vein can cause damage to thoracic duct and Placement of pulmonary artery can cause damage to right lymphatic duct. However, chyle [fat + lymph] in thorax is usually caused by the damage to thoracic duct because this duct originates from abdomen so it contains fat along lymph. Thus, central line to left internal jugular vein will be more likely to cause chylothorax

This is the only choice that comes close to nicking the thoracic duct, specifically at its inlet, the left subclavian.
