A.	The latter are not distributed, like transmission lines
B.	The former can use stubs and quarter-wave transformers, unlike the latter
C.	Transmission lines use the principal mode of propagation, and therefore do not suffer from low-frequency cutoffs
D.	Terms such as impedance matching and standing wave ratio cannot be applied to waveguides
