Solution

The correct option is A only if the frequency of radiation is above a certain threshold value
Electrons are emitted from the surface of a metal when its exposed to light. This is called photoelectric effect. Each metal has a certain threshold frequency of light when an electron is emitted. Above this frequency, the electron is emitted and the extra energy is transferred to the electron
