Correct answer choice is :

D) Constantine reunited the empire and served as sole ruler, while Diocletian divided the empire and shared emperor duties.

Explanation:

Constantine established regulatory, economic, social, and military changes to sustain the empire. He restructured the government, dividing civil and military rights. To fight extension he launched the solidus, a new gold coin that became the standard for Byzantine and European currencies for more than a thousand years. Diocletian divided and expanded the empire's civil and military services and organized the empire's provincial divisions, building the largest and most bureaucratic government in the chronicle of the empire. He set new regulatory centers in Nicomedia, Mediolanum, Sirmium, and Trevorum, closer to the empire's frontiers than the legendary capital at Rome.
