When did Arab Spring began?

2010

The correct answer is option 3 - 2010

The Arab Spring began in December 2010 in Tunisia, following the self-immolation of Mohamed Bouazizi, a street vendor protesting police harassment and government corruption. This sparked mass protests that led to the fall of the Tunisian government and inspired similar uprisings across the Arab world, including in Egypt, Libya, Syria, Yemen, and others.
