Please help answer.

A blue laser beam is incident on a metallic surface, causing electrons to be ejected from the metal. If the
frequency of the laser beam is increased while the intensity of the beam is held fixed,
the rate of ejected electrons will remain the same but their maximum kinetic energy will increase.
the rate of ejected electrons will increase and their maximum kinetic energy will increase
the rate of ejected electrons will decrease and their maximum kinetic energy will increase.
the rate of ejected electrons will remain the same but their maximum kinetic energy will decrease
