The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Full Form of ADH:** - ADH stands for Anti-Diuretic Hormone. 2. **Know the Alternative Name:** - ADH is also known as Vasopressin. 3. **Understand the Function of ADH:** - The primary function of ADH is to stimulate the reabsorption of water and electrolytes in the kidneys, specifically in the distal tubules. 4. **Effect on Water Loss:** - By promoting the reabsorption of water, ADH reduces the loss of water through urine, leading to more concentrated urine. 5. **Evaluate the Options:** - Option 1: Increases water absorption - This is correct. - Option 2: Decreases water absorption - This is incorrect. - Option 3: Synthesizes salt - This is incorrect. - Option 4: Controls sugar level of the body - This is incorrect (this function is performed by insulin). 6. **Conclusion:** - The correct answer is Option 1, which states that ADH increases water absorption. ---
