- Carbon monoxide (CO) affects oxygen transport in blood, causing headaches. - Carbon dioxide (CO2) (B) is a greenhouse gas responsible for global warming → (I). - Sulphur dioxide (SO2) (C) is a major contributor to acid rain, which damages ecosystems → (II). - Nitrogen dioxide (NO2) (D) is a key contributor to acid rain and photochemical reactions in the atmosphere → (II).
A. Carbon monoxide (CO): This toxic gas reduces the oxygen-carrying capacity of blood, leading to IV. Headache, blurred vision.
B. Carbon dioxide (CO2): A primary greenhouse gas contributing to I. Global warming.
C. Sulphur dioxide (SO2): A major component of II. Acid rains.
D. Nitrogen dioxide (NO2): A key component of III. Photochemical smog.
Therefore, the correct matching is:
A - IV
B - I
C - II
D - III The correct answer is (1) A-IV, B-I, C-II, D-III.

To solve the problem, we need to match the pollutants with their corresponding effects.
1. Understanding the Pollutants and Their Effects: The pollutants and their effects are as follows:
Carbon monoxide (A): This gas is harmful as it contributes to global warming by trapping heat in the atmosphere.
Carbon dioxide (B): This gas is a major contributor to acid rains, as it reacts with water vapor in the atmosphere to form acidic compounds.
Sulphur dioxide (C): This gas is primarily responsible for causing photochemical smog, which can damage the lungs and cause respiratory problems.
Nitrogen dioxide (D): This pollutant is known to cause headaches and blurred vision due to its toxic effects on the human body.
2. Analyzing the Matching: - A (Carbon monoxide) corresponds to IV (Headache, blurred vision). - B (Carbon dioxide) corresponds to I (Global warming). - C (Sulphur dioxide) corresponds to III (Photochemical smog). - D (Nitrogen dioxide) corresponds to II (Acid rains).
3. Conclusion: Based on the analysis, the correct matching is:
Final Answer: The correct option is (A) A-IV, B-I, C-II, D-III.
