• A. anthropogenic activities such as deforestation and industrialisation.
• B. ozone layer depletion
• C. naturally occurring greenhouse gases in the earth’s atmosphere
• D. population explosion

Answer 1

The correct option is A anthropogenic activities such as deforestation and industrialisation.

Global warming is an increase in the average surface temperature of the earth. This happens when there is an increase in the amounts of greenhouse gases in the atmosphere, beyond normal levels, upsetting the natural greenhouse effect. Such an increase is mostly the result of human activities such as burning fossil fuels, deforestation, careless disposal of various kinds of wastes etc.
