Options

A. Bile juice
B. Intestinal juice
C. Pancreatic juice
D. Pancreatic hormone

Explanation

**Step-by-Step Solution:**

1. **Understanding Enterokinase**: Enterokinase is an enzyme that plays a crucial role in the digestive process. It is responsible for converting trypsinogen, an inactive enzyme, into its active form, trypsin.

2. **Identifying the Location**: The question asks where enterokinase is found among the options: bile juice, intestinal juice, pancreatic juice, or pancreatic hormone.

3. **Analyzing the Options**:
- **Bile Juice**: This is primarily involved in the emulsification of fats and does not contain enterokinase.
- **Pancreatic Juice**: This contains digestive enzymes but does not include enterokinase.
- **Pancreatic Hormone**: This refers to hormones like insulin and glucagon, which are not enzymes and do not include enterokinase.
- **Intestinal Juice**: This is secreted by the intestinal glands and contains various enzymes, including enterokinase.

4. **Conclusion**: Since enterokinase is specifically found in the intestinal juice, the correct answer is **intestinal juice**.

5. **Final Answer**: Enterokinase is present in **intestinal juice** (Option B).
