Answer: the statements that are true for

the photo-electric effect is statement D. ( The frequency of the photons must be larger than a certain minimum value in order to eject electrons from the metal.)

Explanation:In the photo electric effect process, if an electron within some material absorbs the energy of one photon and acquires more energy than the work function (the electron binding energy) of the material, it is ejected.
