The correct Answer is:
To solve the question regarding the assertion and reason about ADH (Antidiuretic Hormone), we can break it down step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "ADH reduces chloride loss in urine." - To evaluate this, we need to know the role of ADH. ADH primarily functions to promote water reabsorption in the kidneys, which can indirectly affect the concentration of other solutes, including chloride. However, it does not specifically reduce chloride loss; rather, it helps retain water, which can lead to a dilution effect on chloride concentration in urine. Thus, the assertion is misleading. 2. **Understanding the Reason**: - The reason states that "ADH decreases water absorption." - This statement is incorrect. The primary function of ADH is to increase water absorption in the kidneys, specifically in the collecting ducts. When ADH is released, it promotes the insertion of aquaporin channels in the kidney tubules, allowing more water to be reabsorbed back into the bloodstream. Therefore, the reason is false. 3. **Conclusion**: - Since both the assertion and the reason are false, the correct option is that both statements are incorrect. ### Final Answer: Both the assertion and the reason are false. ---
