Secretion of pancreatic juice is stimulated by

Options

A. gastrin
B. enterogastron
C. secretin
D. enterokinase

Explanation

**Step-by-Step Solution:**

1. **Understanding Pancreatic Juice**: Pancreatic juice is a digestive fluid produced by the pancreas that contains enzymes and bicarbonate, which help in the digestion of food in the small intestine.

2. **Identifying Stimuli for Secretion**: The secretion of pancreatic juice is influenced by various hormones and factors. It is crucial to identify which of the given options stimulates this secretion.

3. **Analyzing the Options**:
- **Gastrin**: This hormone is primarily involved in stimulating gastric acid secretion in the stomach, not directly in stimulating pancreatic juice secretion.
- **Enterogastron**: This is a hormone that inhibits gastric motility and secretion but does not directly stimulate pancreatic juice secretion.
- **Saccharine**: This is not a hormone related to the stimulation of pancreatic juice; it is a sweetener and does not play a role in digestion.
- **Enterokinase**: This is an enzyme that activates trypsinogen to trypsin but does not directly stimulate the secretion of pancreatic juice.

4. **Correct Answer**: The secretion of pancreatic juice is primarily stimulated by **Secretin**. Secretin is a hormone released by the duodenum in response to the presence of acidic chyme from the stomach. It signals the pancreas to release bicarbonate and enzymes.

5. **Conclusion**: Therefore, the correct answer to the question is **Secretin**.
