Answer:
C. the Romans
Explanation:
The fall of the Roman Empire in the west amid the fifth century did not totally demolish the cursus publicus. Its points of interest were clear to the new savage rulers; a few, for example, Theodoric, lord of the Ostrogoths, who governed Italy from AD 493 to 526, are known to have kept up the fundamentals of the Roman postal framework inside their very own areas. Indeed, even in the mid ninth century, under the Carolingian Empire, the remnants of the cursus publicus seem to have continued, and posthouses were kept up. While the administration did not pursue a regularly organized pattern, it was at least reasonably frequent.
