Answer 1

The correct answer is Silver.

Key Points

Conductivity: The measure of the ease at which an electric charge can pass through a material is called electrical conductivity.
Conductor: The material which has high conductivity is called the conductor.
Non-conductor: The material which has very low conductivity is called non-conductor.
Metal has high conductivity and non-metal has very low conductivity
Electrical Conductivity is the evaluation of a material's ability to allow the transport of an electric charge.
Silver is by far the most electrically conductive metal on earth. Since silver has only one valence electron which is free to move around with little resistance, it has great electrical and thermal conductivity.
After silver, copper is the second most electrically conductive metal. Gold and Aluminium are other metals which are good conductors of electricity.

Additional Information

Material	Description
Glass	Glass is a non-crystalline amorphous solid that often appears transparent and has widespread practical, technological, and decorative applications. Its uses include window panes, drinkware, and optoelectronics. Its most significant characteristics include transparency, brittleness, hardness, and resistance to chemical attack.
Mica	Mica is a group of silicate minerals that are widely distributed in different types of rock. Mica has a crystalline structure that allows it to be split into thin sheets. These sheets are flexible, heat-resistant, and electrically insulating, making mica useful in the electronics and electrical industries, and in the manufacturing of cosmetics.
Ebonite	Ebonite is a type of hard rubber, also known as vulcanite or hard vulcanized rubber. It's made by treating rubber with sulfur at high temperatures, a process known as vulcanization. The resulting material is hard and black, resembling ebony, which gives it its name. Ebonite has high electrical resistance and chemical stability, making it appropriate for applications like electrical insulators and bowling balls. It is also historically used for wind musical instruments like clarinets and mouthpieces of other wind instruments because of its excellent machining properties.
