Question

Match the following:

List-1:                                         List-2:
A Nitrogen oxides                    I Oxygen transport
B Carbon monoxide                 II Biomagnification
C Carbon dioxide                     III Photochemical smog
D Industrial effluents              IV Global warming
                                                  V Increase of BOD

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

Hint:

Remember, industrial pollutants like nitrogen oxides and carbon monoxide can lead to smog and affect oxygen transport, while carbon dioxide contributes to global warming.

Answer 1

The Correct Option is D

- A Nitrogen oxides are primarily responsible for photochemical smog (III).
- B Carbon monoxide is involved in oxygen transport (I), as it can bind to hemoglobin in place of oxygen.
- C Carbon dioxide contributes to global warming (IV) by trapping heat in the atmosphere.
- D Industrial effluents lead to the increase of BOD (V), which impacts water quality.
