Options

A. 0.0015
B. 0.0025
C. `1.5%`
D. `2.5%`

Answer

To determine the concentration of inorganic salts in normal urine of a human being, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Composition of Urine**:
- Normal urine is primarily composed of water, urea, inorganic salts, and other waste materials.

2. **Identify the Percentage Composition**:
- According to the information provided, urine consists of approximately:
- 95% water
- 2.5% urea
- 1.5% inorganic salts
- 1% other waste materials

3. **Focus on Inorganic Salts**:
- From the composition breakdown, we can see that inorganic salts make up 1.5% of the total volume of urine.

4. **Conclusion**:
- Therefore, the concentration of inorganic salts in normal urine of a human being is **1.5%**.

### Final Answer:
The concentration of inorganic salts in normal urine of a human being is **1.5%**.
