Statement-I (S-I) : Automobiles are major cause for air pollution in cities.
Statement-II (S-II) : Increase in the number of vehicles running by fossil fuels increased in recent years.

Options

A. Statement- I and statement- II both are correct
B. Statement- I is correct and statement- II is
C. Statement- I is wrong and statement- II is correct
D. Statement- I and statement- II both are wrong

Answer

To analyze the statements provided in the question, we will evaluate each statement step by step.

### Step 1: Evaluate Statement-I (S-I)
- **Statement-I**: "Automobiles are a major cause of air pollution in cities."
- **Analysis**: Automobiles, which include cars, trucks, and buses, primarily run on fossil fuels such as petrol and diesel. The combustion of these fuels releases various pollutants, including carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate matter into the atmosphere. These pollutants significantly contribute to air quality degradation, particularly in urban areas where vehicle density is high.
- **Conclusion**: Statement-I is **true**.

### Step 2: Evaluate Statement-II (S-II)
- **Statement-II**: "Increase in the number of vehicles running by fossil fuels increased in recent years."
- **Analysis**: Over the past few decades, there has been a notable increase in the number of vehicles on the road, particularly in urban areas. This increase is largely due to population growth, urbanization, and economic development. Most of these vehicles are powered by fossil fuels, which means that as the number of vehicles increases, the emissions associated with their operation also rise. This trend has been observed globally, leading to higher levels of air pollution.
- **Conclusion**: Statement-II is **true**.

### Step 3: Combine the Conclusions
- Since both Statement-I and Statement-II are true, we conclude that the overall assertion made in the question is correct.

### Final Answer
Both Statement-I and Statement-II are correct.
