can anybody tell me HOW????????

The size of the atom of co2 is big to resist the uv rays coming from sun and density of co2 in the atmosphere is also one of the other reason for it.

So I guess the answer is wrong it must be ozone layer because. Ozone absorbs uniquely a band of far infrared radiation, that otherwise has absolutely no harmful effects on life on Earth.

Its seems ozone is the right answer, because carbon traps heat and ozone traps harmful UV rays. Ozone layer holes are dangerous because these allow UV rays from out world and result in skin cancer etc. That is why so much effort is put in conserving ozone layer and ozone depleting substances are either banned or their use is discouraged.

Ozone absorbs ultraviolet rays and CO2 absorbs infrared rays.

Jashan has given the right answer others confused between UV&Infrared rays.

Firstly it is infrared not UV rays. And co2 is considered as one of the most important greenhouse gas as it absorbs the incoming solar radiations. It is co2.

Carbon dioxide has both stretching and bending vibrations. So it absorbs all the infrared radiations strongly.

Co2 absorb infra red radiation, this is the right answer.

Farhan said: (Jan 9, 2015)  
Is ozone not the right answer? Because the question says radiation from sun.

Vineet Swami said: (Mar 17, 2015)  
Infrared radiation is strongly absorbed by water vapour than Co2. Water vapour is less portion in atmosphere but Co2 is high. Due to Co2 in high portion it absorbed high amount of infrared radiation.

Ozone layer absorbs the Infrared radiation by Sun.

Ranjan Kumar Mali said: (May 17, 2016)  
Carbon dioxide is the right answer for infrared radiation.

Thinker said: (Apr 26, 2018)  
CO2 is the right choice. Infrared means heat and co2 as we know it creates the greenhouse effect. The infrared ray is a quit different thing.

Co2 must be the right.
