Text Solution

Verified by Experts

The correct Answer is:
C
Carbon dioxide forms a blanket around the earth and functions like a glass panel of a greenhouse. This allows the sunlight to pass out through it, but does not allow the heat from being re-radiated back into the outer space. This phenomenon is called greenhouse effect. Incomplete combustion of fossil fuels in automobiles releases `80%` carbon monoxide (CO).
