Solution
The correct option is C Radio waves
When the gap size is larger than the wavelength, the wave passes through the gap and does not spread out much on the other side. When the gap size is equal to the wavelength, maximum diffraction occurs. So among all of them radio waves have minimum wavelength and hence it will give maximum diffraction.
