Answer

To determine which organ's removal will have the least effect on an adult human, we need to analyze the functions of the organs listed in the options.

### Step-by-Step Solution:

1. **Identify the Organs**: The question involves evaluating the effects of removing the spleen, liver, pancreas, and pituitary gland.

2. **Assess the Spleen**:
- The spleen is part of the immune system and helps filter blood, but humans can live without it. Other organs, such as the liver and bone marrow, can compensate for some of its functions.
- **Conclusion**: Removal of the spleen has a relatively minor effect on overall health.

3. **Assess the Liver**:
- The liver is crucial for detoxification, metabolism, and producing important proteins. Its removal would lead to severe health issues.
- **Conclusion**: Removal of the liver has a significant negative effect.

4. **Assess the Pancreas**:
- The pancreas produces insulin and glucagon, which are vital for regulating blood sugar levels. Without it, a person would develop diabetes and require insulin therapy.
- **Conclusion**: Removal of the pancreas has a significant negative effect.

5. **Assess the Pituitary Gland**:
- The pituitary gland is known as the "master gland" because it regulates many hormonal functions in the body. Its removal would disrupt numerous body processes.
- **Conclusion**: Removal of the pituitary gland has a significant negative effect.

6. **Final Decision**:
- Based on the analysis, the organ whose removal would have the least effect on an adult human is the **spleen**.

### Final Answer:
The organ whose removal will have the least effect in an adult human is the **spleen**.
