**Step-by-Step Solution:**

1. **Understanding Secretin**: Secretin is a hormone produced in the small intestine. It plays a crucial role in the digestive process.

2. **Location of Action**: Secretin is released into the intestinal lumen, which is the hollow part of the intestine where digestion occurs.

3. **Function of Secretin**: The primary function of secretin is to stimulate the secretion of bicarbonate ions (HCO3-) from the pancreas. This bicarbonate helps to neutralize the acidic chyme that comes from the stomach into the small intestine.

4. **Effect on Pancreatic Juice**: The bicarbonate-rich fluid secreted by the pancreas is part of the pancreatic juice. Therefore, secretin indirectly stimulates the secretion of pancreatic juice.

5. **Conclusion**: Based on the function of secretin, the correct answer to the question is that secretin stimulates the secretion of pancreatic juice.

**Final Answer**: Secretin stimulates the secretion of pancreatic juice.
