Answer: D: They are closed at one end

Explanation:

"Lymphatic Capillaries" are tiny, thin walled microvessels located in spaces between cells and their main function is to drain and process extracellular fluid.

They are larger than blood capillaries and have "closed ends". Their unique structure permits interstitial fluid to flow into them but not out. Thus their ends are closed unlike the loop structure of blood capillaries.
