The correct Answer is:

**Step-by-Step Solution:** 1. **Identify the Location of Gastric Juice:** - Gastric juice is present in the stomach, which is a key organ in the digestive system. 2. **Understand the Importance of pH in Gastric Juice:** - The pH of gastric juice is crucial for the function of protein-digesting enzymes. An acidic environment is necessary for these enzymes to work effectively. 3. **Know the Source of Acidity:** - The acidity of gastric juice is primarily due to the secretion of hydrochloric acid (HCl) by parietal cells in the stomach lining. 4. **Determine the pH Range of Gastric Juice:** - The pH of gastric juice typically ranges from 1.5 to 3.5. This indicates that gastric juice is strongly acidic. 5. **Evaluate the Options Given:** - The options provided include: - 2 (correct) - 4 (incorrect) - 6 (incorrect) - 8 (incorrect) - Since the pH of gastric juice falls within the range of 1.5 to 3.5, the option 2 is valid as it is within this range. 6. **Conclusion:** - Therefore, the pH of gastric juice is approximately 2, which is a strongly acidic medium. **Final Answer:** - The pH of gastric juice is 2. ---
