Pancreatic juice contains the following enzyme
(a) pepsin
(b) trypsin
(c) dipeptidase
(d) enteropeptidase

Options

A. pepsin
B. trypsin
C. dipeptidase
D. enteropeptidase

Explanation

To determine which enzyme is found in pancreatic juice, let's analyze the options provided:

1. **Understanding Pancreatic Juice**:
- Pancreatic juice is an alkaline fluid secreted by the pancreas.
- It contains several digestive enzymes that are crucial for the digestion of proteins, fats, and carbohydrates.

2. **Analyzing the Options**:
- **(a) Pepsin**: This enzyme is primarily found in the stomach and is responsible for protein digestion, but it is not present in pancreatic juice.
- **(b) Trypsin**: This enzyme is secreted by the pancreas and is indeed a major component of pancreatic juice. It helps in the digestion of proteins by breaking them down into smaller peptides.
- **(c) Dipeptidase**: This enzyme is involved in the final stages of protein digestion, but it is not a component of pancreatic juice; it is found in the intestinal brush border.
- **(d) Enteropeptidase**: This enzyme is also not found in pancreatic juice; it is produced in the small intestine and activates trypsinogen (the inactive form of trypsin) into trypsin.

3. **Conclusion**:
- From the analysis, the only enzyme present in pancreatic juice among the given options is **trypsin** (option B).

### Final Answer:
The enzyme present in pancreatic juice is **(b) trypsin**.
