Correct Answer:
D. Arab Spring
The series of massive anti-government protests, uprisings, and armed rebellions that spread across much of the Arab world starting in 2010 is widely known as the Arab Spring. This term encapsulates the wave of revolutionary demonstrations and civil wars that challenged authoritarian regimes in the region. While 'Arab Uprising' or 'Arab Revolution' might describe aspects of these events, 'Arab Spring' is the universally recognized and accepted historical term. 'Islamic Awakening' is a different concept, not directly referring to these specific political movements.
