In a city, a thermal power plant produces a large amount of smoke while generating electricity. Which of the following problems is not a result of the smoke released by the factory?

Options

A. Smog
B. Acid rain
C. Air borne diseases
D. Breathing disorders

Answer

To solve the question, we need to analyze the options provided and determine which one is not a result of the smoke released by a thermal power plant.

### Step-by-Step Solution:

1. **Understand the Source of Smoke**: A thermal power plant generates electricity by burning fossil fuels, which produces smoke containing various pollutants.

2. **Identify the Options**: The options given are:
- A) Acid rain
- B) Airborne diseases
- C) Breathing disorders

3. **Analyze Each Option**:
- **Acid Rain**: This is caused by pollutants like sulfur dioxide (SO2) and nitrogen oxides (NOx) that can be emitted from thermal power plants. These gases can lead to the formation of acid rain when they react with water vapor in the atmosphere.
- **Breathing Disorders**: The smoke from the thermal power plant contains particulate matter and other harmful substances that can lead to respiratory issues, such as asthma and other breathing disorders.
- **Airborne Diseases**: These are diseases caused by pathogens (like viruses and bacteria) that are transmitted through the air. They are not directly caused by smoke or pollutants from a thermal power plant.

4. **Conclusion**: The problem that is not a result of the smoke released by the factory is **B) Airborne diseases**. This is because airborne diseases are caused by microorganisms and not by the smoke or pollutants emitted from thermal power plants.

### Final Answer:
**B) Airborne diseases**
