Answer:
B. New democratic governments are established.
Step-by-step explanation:
The Arab Spring was a period in the early 2010s, that consisted in a series of mass protests and civil unrest in several countries of the MENA region: Middle East and North Africa.
The protests had in common the demand for more democratic forms of governments, the reform or removal of existing authoritarian governments, and changes in social and economic policy.
In a few countries, the Arab spring led to the establishment of new democratic governments, for example, in Tunisia, the country the protests first started. In other countries however, the protests did not lead to positive results, the most extreme cases being Syria and Libya, where civil wars were sparked during the movement.
