The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the unpaired structure in the human excretory system. This means we need to identify which structures are present as single entities, rather than in pairs. 2. **Identifying Structures**: The main components of the human excretory system include: - Kidneys - Ureters - Urinary Bladder - Urethra 3. **Analyzing Each Option**: - **Option A: Ureter**: There are two ureters in the human body (one for each kidney), so this is not unpaired. - **Option B: Kidney**: There are also two kidneys, so this is not unpaired. - **Option C: Urinary Bladder**: There is only one urinary bladder in the human body, making it unpaired. - **Option C: Urethra**: The urethra is also a single structure that serves as the exit for urine from the urinary bladder. 4. **Conclusion**: Since both the urinary bladder and urethra are unpaired structures in the human excretory system, the correct answer is Option C, which includes both the urinary bladder and the urethra. 5. **Final Answer**: The unpaired structures of the human excretory system are the urinary bladder and urethra (Option C). ---
