Which of the following accurately describes what makes a material a good conductor?

A. It must resist neutron flow.

B. It must readily accept electron flow.

C. It must readily accept neutron flow.

D. It must resist electron flow.

Your answer should be D

Answer: Option B

Explanation:

The electrical current is defined as the flow of electrons inside a material.

As more electrons can flow in a given time (for a fixed area, suppose the transversal area of a wire), more electricity is being generated.

Some materials have some resistance to the flow of electrons because they have "obstacles" that impede the free flow of the electrons, and when the electrons hit those obstacles, energy is liberated, this is why some materials heat up as a current flows throw them.

Now, you also may know that as the temperature of an object increases, also the kinetic energy of the particles inside of it, so the particles of the material will be moving a lot more, and because of this, the electrons will find more resistance to the motion.

The correct answer here is B; a good conductor must readly accept the electron flow.
