Match the Global Environmental problems given in Column-I with their causes given in Column-II and choose the correct answer using the codes given below :
Column-I – Column-II
(a) Ozone layer depletion – (i) Emission of CO2, SO2 and N2O
(b) Green house effect – (ii) Extinction of Flora and Fauna
(c) Acid Rain – (iii) Emission of CFCs and chlorinated compounds
(d) Loss of Biodiversity – (iv) Emission of Nitrogen and Sulphur oxides

Question

Accepted Answer

To explain why Option 4 is the correct answer, let's analyze the matching of Global Environmental problems in Column-I with their causes in Column-II:

1. **(a)-iii**: This match indicates that the environmental problem listed in position (a) of Column-I is caused by the factor listed in position (iii) of Column-II. This match is correct based on the factual relationship between the specific problem and its cause.

2. **(b)-i**: This match suggests that the environmental issue in position (b) of Column-I is linked to the cause in position (i) of Column-II. This pairing is accurate because the cause directly leads to the environmental problem specified.

3. **(c)-iv**: Here, the environmental problem in position (c) of Column-I is associated with the cause in position (iv) of Column-II. This is a correct match as the cause is a well-known contributor to the problem listed.

4. **(d)-ii**: This match connects the environmental issue in position (d) of Column-I with the cause in position (ii) of Column-II. This is an appropriate pairing because the cause is a primary factor leading to the environmental problem.

Now, let's explain why the other options are incorrect:

- **Option 1**: The matches in this option do not accurately reflect the established relationships between the environmental problems and their causes. Each pairing in this option fails to align with the known causes of the respective problems.

- **Option 2**: Similar to Option 1, the matches in Option 2 do not correctly associate the environmental issues with their causes. The pairings are inconsistent with the factual causes of the problems listed.

- **Option 3**: This option also contains incorrect pairings. The matches do not correspond to the actual causes of the environmental problems, making this option incorrect.

In conclusion, Option 4 is the correct answer because it accurately matches each environmental problem with its corresponding cause, based on factual information and logical reasoning. The other options fail to provide the correct associations, which is why they are incorrect.
