Smog is a combination of:a.Different types of air pollutants b.Smoke and Fogc.Ozone and Industrial Smoked.Carbon Monoxide and Fog

Sure, let's break down the question step by step to find the correct answer.

1. Understanding Smog: Smog is a type of air pollution that is a combination of various substances. The term "smog" itself is derived from the words "smoke" and "fog."

2. Analyzing the Options:

   • Option a: Different types of air pollutants: While smog does contain various air pollutants, this option is too broad and doesn't capture the specific components that define smog.
   • Option b: Smoke and Fog: This option directly reflects the origin of the term "smog" and accurately describes the combination of smoke (from various sources like industrial emissions, vehicle exhaust, etc.) and fog (which is essentially water droplets suspended in the air).
   • Option c: Ozone and Industrial Smoke: Ozone can be a component of smog, particularly in photochemical smog, but this option doesn't fully capture the traditional definition of smog.
   • Option d: Carbon Monoxide and Fog: Carbon monoxide can be a component of smog, but it is not the primary defining feature. This option is too specific and doesn't encompass the broader components of smog.

3. Conclusion: Based on the analysis, the most accurate and specific definition of smog is given by option b.

Answer: b. Smoke and Fog
