Answer:
D. decrease of military influence in the Roman Empire
Explanation:
The decline in the quality of roads and ports created an economic problem in the Roman Empire, due to the decline in agricultural production and the increase in food prices. Increased food prices led to famine, and riots broke out in certain regions. In addition, this economic crisis directly affected the maintenance of armies located in the limes, the borders of the Roman Empire.
This economic crisis resulted in the diminishing military influence of the Roman army and thus the borders became vulnerable to attacks by barbarian groups. Borders have always been threatened by foreign peoples, but in the second century this threat increased and in the fifth century it became untenable with the migratory flow of the Germans. This event further weakened military influence in Rome.
