The correct option is "Neither 1 nor 2" because the Ionosphere contains a high concentration of charged particles, which enables it to reflect and refract radio waves back to Earth, thereby facilitating long-distance communication. Statement 1 is incorrect as ozone is primarily responsible for absorbing UV radiation rather than reflecting radio waves. Statement 2 is also misleading since radio waves vary in wavelength, but it is primarily the ionization of the Ionosphere, not the wavelength, that allows for effective communication. Therefore, the role of the Ionosphere in radio wave propagation is due to its electrical properties and not the reasons stated in the two options.
