Solution

The correct option is C Short wavelength of electrons.
Illumination with a smaller wavelength results in better resolution (the two spots can be seen as distinct) and this is why the electron microscope produces higher resolution images than the light microscope; because the wavelength of an electron beam is smaller than visible light.
Hence the correct answer is (C)
