Coaxial cables refers to a high-frequency transmission medium that has a single solid-copper core which serves as the conductor in this type of substance.

What is a Conductor?

These are elements which are usually metals and have unique properties such as high conductivity of electricity and heat. This helps for their transmission to be easier and faster due to the metallic properties.

Coaxial cables are high-frequency transmission medium that has a single solid-copper core  which ensures that the signals are optimally moved from one point to another.

This is therefore the reason why it was chosen as the most appropriate choice.
