In photoelectric effect when photons of energy `hnu` fall on a photosensitive surface (work function `hnu_0`) electrons are emitted from the metallic surface with a kinetic energy. It is possible to say that

Options

A. all ejected electrons have same kinetic energy equal to `hnu-hnu_0`
B. the ejected electrons have a distribution of kinetic energy from zero to `(hnu-hnu_0)`
C. the most energetic electrons have kinetic energy equal to `hnu_0`
D. all ejected electrons have kinetic energy `hnu_0`.
