Answer:
The most correct answer would be A.
Explanation:
The thoracic duct carries chyle (lymph + emulsified fats), it drains the lower extremities, pelvis, abdomen, left side of the thorax, left upper extremity, and left side of the head and neck. It starts from T12 (at the cisterna chyli) and extends to the root of the neck, where it drains into the junction of the left subclavian vein and the left internal jugular vein.
