• A. A-IV, B-I, C-II, D-II
• B. A-I, B-I, C-III, D-II
• C. A-II, B-III, C-IV, D-I
• D. A-II, B-IV, C-III, D-I

Hint:

- 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).

Answer 1

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.
