Final answer:
The instability in Libya during 2011 was largely a result of political corruption and a revolution against Muammar Gadhafi's long-standing authoritarian government.
Step-by-step explanation:
The instability in Libya during 2011 was primarily due to a full-scale armed revolution against Muammar Gadhafi's regime. Protestors in Libya were influenced by regional unrest and sought to end Gadhafi's 42-year authoritarian rule. The anti-government rebels initiated the unrest in Benghazi and this escalated into armed conflict, which was supported by the intervention of the North Atlantic Treaty Organization (NATO) with air strikes and a no-fly zone. The protests were fueled by a variety of issues such as high unemployment, poor living conditions, and government corruption. Political instability was compounded by Gadhafi's grip on oil revenues and failure to establish a government that shared power. Consequently, in response to the schoolwork question provided, the most accurate option is (b) Political corruption.
