Answer

**Step-by-Step Solution:**

1. **Understanding Bile**: Bile is a digestive fluid produced by the liver. It is typically greenish in color and plays a crucial role in the digestion of fats in the small intestine.

2. **Components of Bile**: The main components of bile include:
- **Bile Salts**: These are derived from cholesterol and are essential for emulsifying fats, making them easier to digest.
- **Bile Pigments**: The most notable bile pigment is bilirubin, which is a breakdown product of hemoglobin from red blood cells.
- **Cholesterol**: This is also a component of bile and helps in the formation of bile salts.

3. **Identifying the Incorrect Component**: The options provided are:
- A) Bile pigments
- B) Cholesterol
- C) Bile salts
- D) Lipase

Among these, bile pigments, cholesterol, and bile salts are all components of bile. However, lipase is not a component of bile; it is an enzyme secreted by the pancreas that aids in the digestion of fats.

4. **Conclusion**: Therefore, the correct answer to the question "Which of the following is not a component of bile?" is **Option D: Lipase**.
