Gastric juice contains :

Options

A. Pepsin, lipase and rennin
B. Trypsin, lipase and rennin
C. Trypsin, pepsin and lipase
D. trypsin, pepsin and rennin

Answer

To answer the question about the components of gastric juice, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Source of Gastric Juice**:
- Gastric juice is secreted by the gastric glands in the stomach. This is important as it helps us determine which enzymes are present.

2. **List the Main Components of Gastric Juice**:
- The primary components of gastric juice include:
- **Pepsin**: An enzyme that breaks down proteins into smaller peptides.
- **Renin**: An enzyme that curdles milk, primarily found in infants.
- **Lipase**: An enzyme that helps in the digestion of fats.

3. **Eliminate Incorrect Options**:
- **Trypsin**: This enzyme is not present in gastric juice; it is secreted by the pancreas and acts in the small intestine. Therefore, any option containing trypsin can be eliminated.

4. **Evaluate the Remaining Options**:
- After eliminating options containing trypsin, we are left with:
- **Option A**: Pepsin, Renin, Lipase
- **Option B**: Trypsin, Lipase, Renin (eliminated)
- **Option C**: Trypsin, Pepsin, Lipase (eliminated)
- **Option D**: Trypsin, Pepsin, Renin (eliminated)

5. **Confirm the Correct Answer**:
- The only option that correctly lists the components of gastric juice is **Option A**: Pepsin, Renin, and Lipase.

### Final Answer:
Gastric juice contains: **Pepsin, Renin, and Lipase** (Option A).
