Answer:
A. bombarded by high-speed electrons.
Explanation:
Conductors are materials that allows current to pass through them.
However, the flow of current is actually the flow of electrons in the opposite direction.
When a conductor is bombarded by by high-speed electrons, the high speed electrons will repel the electrons in the conductor (in electromagnetism, like charges repel) thus giving them the required kinetic energy to leave the surface of the conductor.
