Options

A. Enterokinase
B. Enterogastrone
C. Gastrin
D. Rennin

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks for the hormone that stimulates the stomach to secrete gastric juice.

2. **Evaluate the Options**: The options provided are:
- Enterokinase
- Enterogastron
- Gastrin
- Ranin

3. **Analyze Each Option**:
- **Enterokinase**: This hormone is secreted from the intestine and activates trypsinogen into trypsin. It does not stimulate gastric juice secretion.
- **Enterogastron**: This hormone is also secreted from the intestine and acts on the stomach to reduce gastric juice secretion and gastric motility. Therefore, it does not stimulate gastric juice secretion.
- **Gastrin**: This hormone is secreted from the stomach itself and stimulates the secretion of gastric juice and increases gastric motility. This matches the requirement of the question.
- **Ranin**: This hormone is present only in a child's stomach and works on milk protein. It is not relevant for stimulating gastric juice secretion in adults.

4. **Conclusion**: Based on the analysis, the hormone that stimulates the stomach to secrete gastric juice is **Gastrin**.

**Final Answer**: Gastrin
