The correct answer is A.
Many populations in Spanish America took advantage of the political situation in Spain to fight for their independence. This was the start of the decolonization of Latin America.
In Mexico, the war of independence was won in 1821. In 1822, after a brief monarchic period, the Republic was declared.
In Brazil, the independence was declared in 1822 after political changes in the country caused by the transference of the Portuguese crown to the Brazilian territory because of Napoleon's threat of invasion of Portugal.
In this period Simon Bolívar, military and political leader tried to unite Latin America based on a Latin-American identity. Because of this, he helped to set free the territories that became Venezuela, Bolívia, and Peru among many others.
