Answer:
B Land region was too large to defend
Explanation:
The fall of the Western Roman Empire is a lengthy process of the decline, as a result of which the state appeared unable to control its vast territory and ceased to exist.
The transition from a republic to an imperial form of government led to the gradual erosion of civil society institutions. The Senate gradually lost its importance, local government was limited, and the judiciary was subordinated to the imperial administration. By the beginning of the 3rd century, the political system turned into a military-bureaucratic monarchy.
After the reign of the “Five Good Emperors” in Rome, the struggle for power intensified and civil wars regularly shook the empire, the culmination of which resulted in a crisis of the 3rd century. This made a blow to the development of crafts and trade, and a number of cities were destroyed. In the Roman Empire, a frequent change of emperors, rulers of provinces, lacking political power, authority and foresight, began to be observed. With the growth of lands controlled by Rome, its fragmentation into provinces also increased. After the land reforms of the Gracchus brothers, subsistence farming began to develop in Rome, which entailed a reduction in the share of the processing industry, and prices for the transportation of goods increased. Trade began to experience extreme decline, which led to the cessation of relations between some provinces.
