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.

A. bombarded by high-speed electrons.
Electrons are emitted from a conductor when the conductor is bombarded by high-speed electrons. This is because the electrons that are already present in the object especially when the object receiver is a metal, water or any object able to conduce electricity, the electrons in these objects are in form of potential energy and when other electrons are in contact with them they move and thus being from potential to kinetic.

VladimirAG [237]

The number of moles of iron produced can be obtained by the use of  stoichiometry.

<h3>What is stoichiometry?</h3>

The term stoichiometry has to do with mass - mole or mass - volume relationships. Stoichiometric relationships could be used to determine the amount of substance.

Now the reaction equation as well as other details are not shown in this question hence a numerical anwer can not be provided. As such, we can know that the balanced reaction equation can always be used to obtain the amount of iron by stoichiometry.
