Answer:

Correct Answer: D

Solution:

  • Carbon dioxide is one of the important green-house gas. It allows the shorter wavelength of infra-red radiations to pass through it but does not allow these radiations to leave the earth’s atmosphere. This results in warming of the atmosphere. If the amount of $ CO _2 $ decreases then there will not be any increase in temperature.
