(c) Pancreas
(d) Intestine

Options

A. Liver
B. Gall bladder
C. Pancreas
D. Intestine

Answer

To solve the question "Which organ stores and concentrates the bile?", we will go through the options provided and analyze them step by step.

### Step-by-Step Solution:

1. **Understanding Bile**: Bile is a digestive fluid produced by the liver. It plays a crucial role in the digestion and absorption of fats.

2. **Identifying the Source of Bile**: The liver is responsible for the production of bile. The liver cells, known as hepatocytes, secrete bile, which contains bile salts, cholesterol, and other components.

3. **Transport of Bile**: After bile is produced in the liver, it does not act immediately. Instead, it is transported through a system of ducts.

4. **Storage of Bile**: The bile travels through the bile ducts and is stored in a specific organ. This organ is responsible for both storing and concentrating the bile.

5. **Identifying the Correct Organ**: The organ that stores and concentrates bile is the gallbladder. It holds the bile until it is needed for digestion, at which point it releases the bile into the small intestine.

6. **Eliminating Other Options**:
- **Liver**: While it produces bile, it does not store it.
- **Pancreas**: This organ produces pancreatic juice, which aids in digestion but does not store bile.
- **Intestine**: The intestine is involved in digestion and absorption but does not store bile.

7. **Conclusion**: Based on the analysis, the correct answer to the question is (b) Gall bladder.

### Final Answer:
(b) Gall bladder
