The answer is the fourth one: right arm.

Explanation for each option:

  1. Left leg: The thoracic duct collects lymph from the left leg. It drains lymph from the lower body, including both legs.

  2. Right foot: The thoracic duct collects lymph from the right foot as it is part of the lower body, which is drained by the thoracic duct.

  3. Left shoulder: The thoracic duct collects lymph from the left shoulder. It drains the left side of the head, neck, chest, and left arm.

  4. Right arm: The thoracic duct does not collect lymph from the right arm. Instead, the right lymphatic duct is responsible for draining lymph from the right arm, right side of the head, and right thorax.

  5. Abdomen: The thoracic duct collects lymph from the abdomen. It drains lymph from the entire lower body and the left side of the upper body.

In summary, the thoracic duct does not collect lymph from the right arm; this is the responsibility of the right lymphatic duct.
