Answer:B-The wavelength of Light is much smaller than wavelength of radio waves

Explanation:

The wavelength of light is much smaller than the wavelength of radio waves so it does not diffract much. Diffraction can be defined as the bending of light around corners of an object and this bending depends on the relative size of object and wavelength. There is a huge difference in light wavelength and building size, therefore, there is no noticeable diffraction
