A) the rate of ejected electrons will remain the same but their maximum kinetic energy will increase.
B) the rate of ejected electrons will remain the same but their maximum kinetic energy will decrease.
C) the rate of ejected electrons will decrease and their maximum kinetic energy will increase.
D) the rate of ejected electrons will increase and their maximum kinetic energy will increase.
