MNP indicates

Options

A. Thermal pollution
B. Atmospheric pollution
C. Faecal pollution
D. Industrial pollution

Answer

### Step-by-Step Solution

1. **Understanding MNP**:
- MNP stands for manufactured nanoparticle pollution. It is important to know what MNP refers to in order to answer the question correctly.

2. **Identifying the Source of MNP**:
- Manufactured nanoparticle pollution is generated from the waste produced by various industries. This indicates that MNP is related to industrial activities.

3. **Analyzing the Options**:
- The options given are:
- A) Thermal pollution
- B) Atmospheric pollution
- C) Faecal pollution
- D) Industrial pollution

4. **Evaluating Each Option**:
- **A) Thermal Pollution**: This refers to the rise or fall in the temperature of a water body due to human activities. Since MNP is not related to temperature changes, this option is incorrect.
- **B) Atmospheric Pollution**: This involves the presence of harmful substances in the atmosphere. MNP does not pertain to air quality, making this option incorrect as well.
- **C) Faecal Pollution**: This is the contamination of water bodies with disease-causing organisms from fecal matter. Since MNP does not relate to fecal contamination, this option is also incorrect.
- **D) Industrial Pollution**: This refers to pollution that arises from industrial activities, which aligns with the definition of MNP as it is generated from industrial waste.

5. **Conclusion**:
- Since MNP is directly linked to waste produced by industries, the correct answer is **D) Industrial pollution**.
