Identify which of the following is not a transmission line?(a) Telepho

1.	Identify which of the following is not a transmission line?(a) Telephone lines(b) Power transmission(c) Underground cables(d) Cavity resonatorsI have been asked this question in an online quiz.This question is from Types of Transmission Lines topic in section Transmission Lines of Electromagnetic Theory
Answer» The correct option is (d) CAVITY resonators To EXPLAIN I would say: The types of transmission LINE are telephone lines, power transmission lines, UNDERGROUND cables, COAXIAL cables, fibre optic cable transmission etc. Cavity resonators are not transmission lines, they are components that aid maximum transmission.
