The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion:** - The assertion states that in the Proximal Convoluted Tubule (PCT), all essential nutrients and 70-80% of electrolytes and water are reabsorbed. - The PCT is indeed a crucial part of the nephron, which is the functional unit of the kidney. It plays a significant role in the reabsorption process. 2. **Understanding the Reason:** - The reason provided explains that the PCT is lined with simple cuboidal brush border epithelium. - This type of epithelium increases the surface area available for reabsorption, which is essential for the efficient absorption of nutrients, electrolytes, and water. 3. **Evaluating the Assertion and Reason:** - Both the assertion and the reason are true. - The reason correctly explains why the assertion is true. The structure of the PCT, with its brush border, enhances the reabsorption capacity. 4. **Conclusion:** - Since both the assertion and the reason are true, and the reason provides a correct explanation for the assertion, we conclude that the assertion is true and the reason is also true, providing a valid explanation. **Final Answer:** - Both the assertion and reason are true, and the reason is the correct explanation of the assertion. ---
