The entrance of certain frequencies through the atmosphere varies depending on the sector. This concept of permittivity by which the rays can enter the earth is called the Radio Window and has a spectrum that ranges from 5MHz to 30GHz. Of the radiation produced by astronomical objects, one part is 'filtered' and the other has the ability to be absorbed by the earth due to its opacity effect.
Ultraviolet rays, X-rays and even gamma rays are completely affected by the ozone layer in Earth's atmosphere.
This makes it difficult to use X-ray telescopes located in Antarctica.
The correct option is D.
