The reason of yellow colour in urine

Options

A. Bile
B. Lymph
C. Cholestrol
D. Urochrome

Explanation

### Step-by-Step Solution:

1. **Understanding Urine Color**: The primary color of urine is yellow. This characteristic color is due to the presence of specific pigments.

2. **Identifying the Pigment**: The yellow color in urine is mainly produced by a pigment known as **urochrome**. Urochrome is a waste product formed from the breakdown of hemoglobin.

3. **Factors Affecting Urine Color**: The color of urine can vary based on the amount of water consumed. When a person is well-hydrated, the urine tends to be lighter in color, while dehydration leads to darker urine.

4. **Concentration of Urine**:
- **Concentrated Urine**: When urine is concentrated (due to low water intake), it appears dark yellow.
- **Dilute Urine**: Conversely, when urine is dilute (due to high water intake), it appears pale yellow.

5. **Conclusion**: The yellow color of urine is primarily due to the pigment urochrome, and its intensity can vary based on hydration levels.
