D)Copper

Question

Quizplus · Accepted Answer

Teflon is a widely used material as the dielectric in transmission lines due to its high dielectric strength, low loss tangent, and high thermal stability. It can withstand high operating temperatures and has a low coefficient of thermal expansion. Pyrex is also sometimes used but is less common than Teflon. Rubber and copper are not suitable as dielectric materials.
