Correct Answer is C
Explanation
A. Bronchomediastinal duct and subclavian duct: bronchomediastinal and subclavian are lymphatic trunks, not the two major collecting ducts.
B. Right and left thoracic ducts: there is a single thoracic duct (left-sided) and a separate right lymphatic duct; we do not have distinct “right and left thoracic ducts.”
C. Thoracic duct and right lymphatic duct: the thoracic duct drains most of the body into the left subclavian vein, and the right lymphatic duct drains the right head/neck, right upper limb, and right thorax into the right subclavian vein.
D. Lumbar duct and left lymphatic duct: “lumbar duct” is not a collecting duct term used in this context, and “left lymphatic duct” is another name sometimes used for the thoracic duct but paired with “lumbar duct” is not the standard two-collector pair.
Correct Answer is B
