Answer: (A)

Coax runs carry RF video signals and are typically 75 ohms. When distributing TV signals to multiple outlets, you want the circuit to continue beyond the outlet while still delivering a drop to the local device. Having two 75-ohm cables at each outlet provides a drop to the device and a through (pass-through) path to feed the next outlets in the chain. This keeps the signal flow intact across the entire installation and avoids needing extra splitters inside the wall box, making the system easier to expand and better preserves signal quality. In Unit Grade 2 practice, this two-cable-per-outlet approach is the standard to ensure a scalable, continuous distribution.
