Answer:
C). He established a different currency for each of the provinces.
D). He adopted a monotheistic religion.
E). He founded the construction of across his empire.
Explanation:
Darius was able to take a hold of such a huge empire as he established the 'provincial government' and employed 'provincial governors' to ensure effective control over these provinces as the empire was too large to be handled alone.
As per the question, Darius 'established a separate currency for each province' that would assist him to have authority over them. Then, he adopted a 'monotheistic religion' that united these provinces in a single thread. 'The construction of across his empire' to ensure the safety and security of his empire from any kind of potential attack or intrusion. Thus, options C, D, and E are the correct answers.
