03.02 electric current which type of materials structure that makes them good conductors. Explain understanding this relationship can help people design more efficient technologies

For a material structure to be a good conductor of electricity, the electricity passing through it must be able to move the electrons within them, therefore, the more free electrons in a metal, the greater its conductivity.

Explanation:

Examples of materials that conduct electricity are, silver, gold and even copper and aluminum etc. Silver is the best conductor of electricity and high light reflectance because it contains a higher number of movable atoms (that is free electrons within), but copper is used widely because of low cost than silver and gold. Gold is also used due to it high resistance to corrosion.

i wanna say it’s between b and d, leaning more towards b.
