Infrared rays are effectively absorbed in the lower boundary of the troposphere. Because it has a greater wavelength. And co2 is a greenhouse gas.
So, the right answer is (D).
So, the right answer is (D).

Infra red rays have high wave length & when it is reflected, co2 gases absorbed this. So the answer is D.

CO2 is major greenhouse gas and absorbs light energy of greater wavelength like infrared radiation. When light energy is absorbed it gets converted into heat or thermal energy. As we move towards upper layers in the troposphere, temperature goes on decreasing and air becomes cooler. It expands due to decrease in pressure.

Infra is one of most power.

What is the reason the infra red rays only vibrate?

Wavelength of light is 300000000. So in troposphere there is O2 is present, presence of O2 CO2 absorbing.
