Answer :
The correct answer is A, as the statement is true. Once the Latin American Wars of Independence ended, these countries were involved in a series of political conflicts that submerged the region in chaos. The main conflict was to define the system of government and state organization of these countries. There were civil wars that devastated the newly independent populations, and that delayed their political and institutional consolidation for several years.
For example, the Argentine War of Independence ended in 1816, with the victory of the independence movement. As soon as this war was over, an internal conflict began that lasted until 1880, between those who sought a unitary system of government and those who wanted to impose federalism. This conflict caused the Argentine Constitution to be drafted in 1853, 37 years after its independence.
