Options

A. trypsin, pepsin, lipase
B. pepsin, lipase, rennin
C. pepsin, amylase, trypsin
D. pepsin, rennin, carboxypeptidase

Answer

**Step-by-Step Solution:**

1. **Understanding Gastric Juice**: Gastric juice is a digestive fluid produced in the stomach, which plays a crucial role in the digestion of food.

2. **Components of Gastric Juice**:
- **Pepsin**: This is the main enzyme in gastric juice responsible for breaking down proteins into peptides. It is secreted in an inactive form called pepsinogen, which is activated by hydrochloric acid (HCl) present in the gastric juice.
- **Renin**: This enzyme is present in the gastric juice of infants and helps in the digestion of milk by curdling it.
- **Lipase**: A small amount of gastric lipase is also present, which helps in the digestion of fats.

3. **Conclusion**: The main components of gastric juice are:
- Pepsin
- Renin (only in infants)
- Lipase

4. **Final Answer**: Therefore, the gastric juice contains pepsin, renin, and lipase.
