Explanation

To determine the hormone that stimulates the stomach to secrete gastric juice, let's analyze the options provided:

1. **Identify the options**: The options given are:
- Option 1: Gastric
- Option 2: Enterogastrone
- Option 3: Enterokinase
- Option 4: Secretin

2. **Understand the function of each hormone**:
- **Gastric**: This hormone is known to stimulate the secretion of gastric juice in the stomach.
- **Enterogastrone**: This hormone is released from the small intestine and inhibits gastric secretion, not stimulates it.
- **Enterokinase**: This is an enzyme that activates pancreatic enzymes but does not stimulate gastric juice secretion.
- **Secretin**: This hormone is also released from the small intestine and primarily stimulates the pancreas to secrete bicarbonate, not gastric juice.

3. **Analyze the correct option**: Based on the functions of these hormones, the hormone that directly stimulates the stomach to secrete gastric juice is **Gastric**.

4. **Conclusion**: Therefore, the correct answer is **Option 1: Gastric**.
