Choose the correct answer among the following :
Gastric juice contains

Options

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

Answer

To solve the question regarding the components of gastric juice, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Components of Gastric Juice**:
- Gastric juice is a digestive fluid produced in the stomach. It contains several components that aid in digestion.

2. **Identify the Key Enzymes**:
- The main enzymes present in gastric juice include:
- **Pepsin**: A protein-digesting enzyme that breaks down proteins into smaller peptides.
- **Renin**: An enzyme that curdles milk, primarily found in infants.
- **Gastric Lipase**: An enzyme that helps in the digestion of fats, though it is present in small amounts.

3. **Evaluate the Options**:
- **Option 1**: Pepsin, Renin, and Gastric Lipase - This option includes all three enzymes that are indeed present in gastric juice.
- **Option 2**: Pepsin, Renin, and Trypsin - This option is incorrect because trypsin is a pancreatic enzyme and not found in gastric juice.
- **Option 3**: Amylase, Pepsin, and Renin - This option is also incorrect as amylase is not present in gastric juice; it is found in saliva and the pancreas.
- **Option 4**: Pepsin, Gastric Lipase, and Trypsin - This option is incorrect for the same reason as option 2; trypsin is not part of gastric juice.

4. **Select the Correct Answer**:
- Based on the evaluation, **Option 1** (Pepsin, Renin, and Gastric Lipase) is the correct answer as all these components are indeed found in gastric juice.

### Final Answer:
**The correct answer is Option 1: Pepsin, Renin, and Gastric Lipase.**
