D. The use of fiber optics to transmit a digital signal.

Reason: Fiber optics use light waves that can carry large amounts of data over long distances with low loss and low interference, making them much more reliable and higher-capacity than printed media, postal mail, or door-knocking (which are not practical wave-based long-distance communication methods).
