Question

Match the items in List I with items in List II

 

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

Hint:

To solve matching-type questions, identify the primary environmental impact associated with each pollutant based on known chemical behavior or atmospheric processes.

Answer 1

The Correct Option is D

Step 1: Carbon monoxide → Greenhouse effect (I)
Carbon monoxide (CO) contributes indirectly to the greenhouse effect by increasing methane levels in the atmosphere and reducing the natural cleansing capacity.

Step 2: Hydrocarbons → Photochemical smog (II)
Hydrocarbons are major precursors in the formation of photochemical smog, especially when reacting with nitrogen oxides in sunlight.

Step 3: Oxides of nitrogen → Acid rain (III)
Nitrogen oxides (NO and NO₂) react with water vapor to form nitric acid, contributing to acid rain.

Step 4: Ozone near earth's surface → Impaired plant growth (IV)
Tropospheric ozone is a harmful pollutant and oxidant that inhibits photosynthesis and impairs plant growth.
