Which type of transmission line accepts the TEM wave?(a) Copper cables

1.	Which type of transmission line accepts the TEM wave?(a) Copper cables(b) Coaxial cable(c) Rectangular waveguides(d) Circular waveguidesI have been asked this question at a job interview.This is a very interesting question from Transverse Electric Magnetic Waves(TEM) in chapter Waveguides of Electromagnetic Theory
Answer» RIGHT OPTION is (b) Coaxial cable Explanation: Hollow TRANSMISSION lines support TE and TM waves only. The TEM wave is possible only in the coaxial cable transmission line, which is not hollow.
