The correct answer is: B. Glass
Dielectrics are materials that do not conduct electricity. They are used in capacitors, which store electrical energy. The dielectric constant of a material is a measure of its ability to store electrical energy. Glass has a dielectric constant of about 7, while air has a dielectric constant of about 1. This means that glass is a much better dielectric than air.
Bakelite and paper are also dielectrics, but they are not as good as glass. Bakelite has a dielectric constant of about 4, and paper has a dielectric constant of about 2.
In conclusion, glass is the most superior dielectric out of the following options.
