Answer

To solve the question "The duodenum receives bile from the following," we need to analyze the options provided and understand the anatomy and physiology of the digestive system.

### Step-by-Step Solution:

1. **Understand the Role of the Duodenum**:
- The duodenum is the first part of the small intestine, where the majority of chemical digestion occurs. It receives digestive juices from various organs.

2. **Identify the Source of Bile**:
- Bile is produced by the liver. It plays a crucial role in the emulsification of fats and is essential for digestion.

3. **Pathway of Bile**:
- After being produced in the liver, bile is stored in the gallbladder. When food enters the duodenum, bile is released from the gallbladder into the duodenum through the bile duct.

4. **Evaluate the Options**:
- **Option 1: Pancreas** - The pancreas produces pancreatic juice, which contains digestive enzymes but does not produce bile. Therefore, this option is incorrect.
- **Option 2: Gallbladder** - The gallbladder stores bile and releases it into the duodenum. This option is correct.
- **Option 3: Both 1 and 2** - Since the pancreas does not provide bile, this option is incorrect.
- **Option 4: None** - This option is also incorrect because the gallbladder does provide bile to the duodenum.

5. **Conclusion**:
- The correct answer is that the duodenum receives bile from the gallbladder.

### Final Answer:
The duodenum receives bile from the gallbladder.
