Answer 1

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.
