To solve the question "Which one of the following is the main graveyard of RBCs?" we need to analyze the functions of the given options: spleen, liver, gallbladder, and kidney.

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for the organ that is primarily responsible for the destruction and recycling of red blood cells (RBCs).

2. **Evaluate Each Option**:
- **Spleen**: The spleen is known for filtering blood and is responsible for the destruction of old and damaged RBCs. It acts as a graveyard for these cells, where they are broken down and their components recycled.
- **Liver**: The liver has many functions, including regulating chemical levels in the blood and producing bile, but it is not primarily responsible for the destruction of RBCs.
- **Gallbladder**: The gallbladder's main function is to store bile produced by the liver. It does not have a role in the destruction of RBCs.
- **Kidney**: The kidneys filter waste products and excess fluids from the blood, but they do not play a significant role in the destruction of RBCs.

3. **Identify the Correct Answer**: Based on the functions of the organs listed, the spleen is the organ that primarily destroys old and damaged RBCs. Therefore, it is referred to as the "graveyard" of RBCs.

4. **Conclusion**: The correct answer to the question is the **spleen**.

### Final Answer:
The main graveyard of RBCs is the **spleen**.
