Answer:
(c) encouraging economic development and democratization.
Explanation:
Civil wars result in a country where some groups or a sect of a country believe that their interest and opinions on national matters are neglected. This leads to a desire for self-rule. Economic development that affects every section of a country and the consideration of the opinions of every sect of the country in national issues will help avert civil war. This is because, every individual will feel involved in the policies and government of the day and will have a sense of believe on the system thus quelling any form of unrest and dissatisfaction with the system.
