the kidneys are in the lumbar region.
the urinary bladder sits in the pelvic cavity.
the urethra transports urine from the kidney to the urinary bladder.
the ureter transports urine to the outside of the body

Explanation:

1. Analyze "The kidneys are in the lumbar region": Kidneys are retroperitoneal and located in the lumbar (lower back) region, so this is correct.
2. Analyze "The urinary bladder sits in the pelvic cavity": The urinary bladder is in the pelvic cavity, supported by pelvic organs, so this is correct.
3. Analyze "The urethra transports urine from the kidney to the urinary bladder": Ureters (not urethra) carry urine from kidneys to bladder. Urethra carries urine out of the body, so this is incorrect.
4. Analyze "The ureter transports urine to the outside of the body": Ureters carry urine from kidneys to bladder; urethra carries to outside. So this is incorrect.

Answer:

A. The kidneys are in the lumbar region, B. The urinary bladder sits in the pelvic cavity
