To analyze the events listed and trace them in chronological order, we need to know the timelines of each event:
- Protests in Tunisia - The protests known as the Jasmine Revolution began in December 2010 and led to the ousting of President Zine El Abidine Ben Ali in January 2011.
- The Islamic Revolution - This refers to the Iranian Revolution, which took place in 1979, leading to the overthrow of the Shah of Iran and the establishment of the Islamic Republic.
- The invasion of Afghanistan - The Soviet Union invaded Afghanistan in December 1979, leading to a prolonged conflict that lasted throughout the 1980s.
- The Gulf War - The Gulf War, initiated by Iraq's invasion of Kuwait in August 1990, resulted in military action in January 1991.

- The Islamic Revolution (1979)
- The invasion of Afghanistan (1979)
- The Gulf War (1990-1991)

So, the correct answer is:
