Answer 1

Answer: (A), (B)

The correct options are
A Carbon dioxide is a greenhouse gas.
B Greenhouse effect leads to global warming.

The greenhouse gases do not let the radiations from the sun entering our atmosphere escape from the Earth. Thus it enhances the average surface temperature of the Earth which leads to global warming, i.e., an increase in the ambient temperature of the Earth causing several disasters.
The gases responsible for greenhouse effect are:
- Water vapour
- Carbon dioxide
- Methane
- Ozone
