The WAN transmission medium that is the fastest and can travel the longest distance is fiber, option D.
Fiber optic cables use light to transmit data, which allows for much faster data transfer rates than other transmission mediums. They also have very low signal loss and can transmit data over very long distances without needing signal boosters or repeaters.
Copper cables, on the other hand, use electrical signals to transmit data, which are slower and more susceptible to interference and signal loss. While they can transmit data over relatively long distances, the quality of the signal degrades over distance and requires signal boosters or repeaters to maintain performance.
Satellite transmission can cover long distances, but it has a higher latency due to the time it takes for the signal to travel to and from the satellite, which can impact real-time applications like video conferencing or online gaming.
Wireless transmission can also cover long distances, but it can be impacted by interference from other wireless signals or physical obstacles like buildings or trees.
In summary, fiber optic cables offer the fastest data transfer rates and the ability to travel long distances without signal degradation, making them the ideal choice for WAN transmission when high performance is required.
