The Correct Answer is D

b. Ureters are fibrotic tubes connecting the kidneys to the urinary bladder: Ureters are not fibrotic; they are muscular tubes lined with a mucous membrane that propels urine from the kidneys to the bladder.
c. Ureters are covered by an outer layer of epithelial tissue: The outermost layer of the ureters is actually composed of connective tissue (adventitia), not epithelial tissue.
