Which epithelium lines the urinary system and has the ability to distend?

Explanation:
Transitional epithelium lines the urinary tract and can distend. Also called urothelium, this tissue is specialized to handle the urine environment while accommodating volume changes. It stretches as the bladder fills, changing from a thicker, more layered appearance when relaxed to a thinner, flatter surface when stretched, thanks to its umbrella cells and tight junctions that preserve a barrier against urine. This design lets the urinary organs expand without tearing the lining. The other options aren’t lining epithelia of the urinary tract or aren’t built to distend in this way—they’re either different epithelial types that don’t stretch in this context, or connective tissue, which doesn’t line a lumen.
