mark for review (will be highlighted on the review page)

Explanation:

To determine the correct order of liquid waste excretion, we recall the urinary system's function: Kidneys filter waste to form urine. Urine then travels through ureters to the urinary bladder for storage. Finally, urine is expelled via the urethra.

• Option A: Follows Kidneys → Ureters → Urinary Bladder → Urethra, matching the correct pathway.
• Option B: Incorrectly starts with Urethra and reverses the flow.
• Option C: Incorrectly places Ureters before Kidneys.
• Option D: Incorrectly orders Urethra and Ureters, and misplaces them relative to Kidneys and Bladder.

Answer:

A. Kidneys → ureters → urinary bladder → urethra
