($A$) Relative change in the radii of two consecutive orbitals does not depend on $Z$
($B$) Relative change in the radii of two consecutive orbitals varies as $1 / n$
($C$) Relative change in the energy of two consecutive orbitals varies as $1 / n^3$

$A.$ The square of maximum velocity of photoelectrons varies linearly with frequency of incident light.
$B.$ The value of saturation current increases on moving the source of light away from the metal surface.
$C.$ The maximum kinetic energy of photo-electrons decreases on decreasing the power of LED (light emitting diode) source of light.
$D.$ The immediate emission of photo-electrons out of metal surface can not be explained by particle nature of light/electromagnetic waves.
$E.$ Existence of threshold wavelength can not be explained by wave nature of light/electromagnetic waves.
