When light of frequency $v$ is incident on a metal,photoelectrons are emitted. This is because...

  • A
    The maximum energy of photoelectrons depends on the intensity of light.
  • B
    The maximum energy of photoelectrons is constant.
  • C
    If $v$ is less than $W/h$,no electrons are emitted,where $W$ is the work function of the metal.
  • D
    The emission of photoelectrons is instantaneous.
