Answer:
Option 4, went on strike, is the right answer.
Step-by-step explanation:
Citizens in ancient Rome were divided into two classes: the plebeians and the patricians. In this classification, the patricians were the people belonging to the wealthy upper-class. All others were regarded as plebeians.
After serving for a long time, the plebeians around 494 BC, started to fight against the dominion of the patricians. This very event in the history of Rome came to be known as the "Conflict of the Orders." In this event, the plebians went on strike to protest against the patricians.
