C

D
lymph ducts
Explanation: 

Detailed explanation-1: -Collecting ducts: Lymphatic vessels empty the lymph into the right lymphatic duct and left lymphatic duct (also called the thoracic duct). These ducts connect to the subclavian vein, which returns lymph to your bloodstream. The subclavian vein runs below your collarbone.

Detailed explanation-2: -Lymph from the right side of the head, right trunk, and right arm drains into the right lymphatic duct. Lymph from the remainder of the body drains into the thoracic duct, which empties into the thoracic vena cava.

Detailed explanation-3: -The two major lymphatics of the body include the right lymphatic duct and the thoracic duct. The right duct drains most of the right upper quadrant whereas the thoracic duct drains the lower body including the extremities and abdomen. To ensure that fluid does not flow backward, all lymphatic have one-way valves.
