Correct Answer – Option 3 – industrialization has increased the amount of carbon dioxide in the air

Increase in carbon dioxide leads to the green house effect leading to the overall increase in temperature at Earth’s surface.

Destruction of decomposers does not cause an increase in temperature. Hence, option 1 is incorrect.

Trees consume carbon dioxide to release oxygen. Hence, deforestation will lead to an increase in the level of oxygen. So, option 2 is incorrect.

Plants – crops again consume carbon dioxide to generate oxygen. And oxygen in the atmosphere does not lead to depletion of ozone layer. Hence, option 4 is incorrect.
