Answer

To arrange the given components in a sequence, we will follow the flow of lymphatic fluid from its origin to its final destination. Here’s the step-by-step solution:

1. **Lymph Capillaries**: These are the smallest and most basic units of the lymphatic system. They are thin-walled structures that collect excess interstitial fluid from tissues, which is then called lymph. Lymph capillaries are found throughout the body and are the starting point of the lymphatic system.

2. **Lymph Vessels**: After the lymph is collected by the lymph capillaries, it drains into larger lymph vessels. These vessels transport the lymph away from the capillaries and towards larger lymphatic structures.

3. **Lymphatic Duct**: The lymph vessels eventually converge into larger ducts. The main lymphatic ducts are the right lymphatic duct and the thoracic duct. These ducts are responsible for draining lymph into the bloodstream.

4. **Subclavian Vein**: Finally, the lymph from the lymphatic ducts is emptied into the subclavian veins, which are located near the collarbone. This is where the lymph re-enters the circulatory system.

Thus, the correct sequence is:
b. Lymph Capillaries → a. Lymph Vessels → c. Lymphatic Duct → d. Subclavian Vein
