The correct Answer is:
To analyze the given statements, we will break down the information regarding classical smog and evaluate each statement step by step. ### Step-by-Step Solution: 1. **Understanding Classical Smog**: - Classical smog is a type of air pollution that is typically formed in cool and humid climates. It is characterized by the presence of sulfur dioxide (SO2) and particulate matter, which are primarily produced from the combustion of fossil fuels. 2. **Evaluating Statement 1**: - **Statement 1**: "Classical smog occurs in cool and humid climate." - This statement is true. Classical smog is indeed associated with cool and humid conditions, which facilitate the formation of this type of smog. 3. **Evaluating Statement 2**: - **Statement 2**: "It is also termed as oxidising smog." - This statement is false. Classical smog is not referred to as oxidizing smog; instead, it is often referred to as reducing smog. This is because sulfur dioxide (SO2), a major component of classical smog, acts as a reducing agent in chemical reactions. 4. **Conclusion**: - Based on the evaluations: - Statement 1 is true. - Statement 2 is false. - Therefore, the correct option is that Statement 1 is true and Statement 2 is false. ### Final Answer: The correct answer is: **Statement 1 is true, and Statement 2 is false.**
