D) unshielded twist pair
E) coaxial cable

Question

Quizplus · Accepted Answer

Signals attenuate most quickly when they travel through the air (or atmosphere) due to factors such as reflection, refraction, and absorption. Fiber optic cables, such as single-mode and multi-mode fibers, have significantly less signal attenuation compared to other transmission media such as unshielded twisted pair and coaxial cables.
