Explanation:
A is the answer! OR B.......
1 and 4 are the best choices since The barbarian attacks killed many romans and the Huns sacked hundreds of cities in the Roman Empire and caused chaos. I also believe 4 is another reason for the decline, since the religion started about 400 years before the fall of the empire and sparked many different believes and divided the Empire through religion.
The answer is: the patricians were more powerful than the plebeians and only free male citizens could vote and hold public office. Hope this helps :)
