• B. Causes: peasant uprisings; Responses: abolition of slavery
• C. Causes: external trade disputes; Responses: universal free trade
• D. Causes: religious reform; Responses: ecumenical councils

Answer: (B)

The important idea here is that the Crisis of the Third Century was a period when the Roman state faced intense internal and external pressure and struggled to keep itself together, followed by deliberate reforms aimed at restoring stability. The root causes were not a single issue but a mix of political breakdown, military power seeping into politics, invasions on frontiers, and economic strain from coin debasement and disrupted taxation and trade. Roman emperors changed rapidly, generals could claim rule by force, frontiers were under pressure from Germanic tribes in the west and Persian fronts in the east, and the economy suffered as money lost its value and the state’s revenues became unreliable.

The strongest answer links these causes to the major responses that historians emphasize. Diocletian’s tetrarchy was not just a change in leadership style; it was an attempt to curb the endless civil wars by sharing power between two senior emperors and two junior co-rulers, so that the army and provinces would have a clearer succession and more stable governance. Administrative reform reorganized provinces and the bureaucracy to improve control and tax collection, while monetary stabilization sought to halt the runaway inflation that weakened the empire’s finances. Together, these measures reflect the era’s characteristic move from ineffective, fractious rule to a more centralized, bureaucratic system designed to endure beyond the lifetime of one charismatic commander.

Other options miss the mark because they center on issues that were not the driving forces of the crisis—peasant uprisings and slavery abolition, external trade disputes with a focus on free trade, or religious reforms and ecumenical councils. While such topics mattered in later periods, they do not capture the core pressures and the key responses of the Crisis of the Third Century.
