Answer

To answer the question regarding the hormone produced in the stomach upon the mechanical stimulation by the entry of food, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the hormone produced in the stomach when food enters. We need to identify the correct hormone from the given options.

2. **Identifying the Options**: The options provided are:
- A. Progesterone
- B. Secretin
- C. Gastrin
- D. Pancreozyme

3. **Analyzing Each Option**:
- **Progesterone**: This is a hormone primarily involved in the menstrual cycle and pregnancy. It is not related to the digestive process in the stomach.
- **Secretin**: This hormone is produced in the small intestine and helps regulate the pH of the small intestine by stimulating the pancreas to release bicarbonate. It is not produced in the stomach.
- **Gastrin**: This hormone is produced by the gastric mucosa in the stomach. It is secreted in response to the presence of food and stimulates the gastric glands to secrete gastric juices, including pepsinogen and hydrochloric acid.
- **Pancreozyme**: This is not a hormone but rather a term that could refer to digestive enzymes produced by the pancreas.

4. **Conclusion**: Based on the analysis, the correct hormone that is produced in the stomach upon the entry of food is **C. Gastrin**.

### Final Answer:
The hormone produced in the stomach upon the mechanical stimulation by the entry of food is **C. Gastrin**.
