Answer:
The correct answer is C. The country that achieved independence not through revolution but by the declaration of a member of the royal family was Brazil.
Step-by-step explanation:
The Independence of Brazil comprises a series of political events that occurred between 1821 and 1824, most of which included conflicts between Brazil and Portugal, giving way to the proclamation of independence presented by the Empire of Brazil on September 7, 1822. It was an important period in the history of the country and differs from the rest of Spanish-American wars of independence in that the process was led by a member of the royal family, the inheriting prince Pedro I, who would become emperor.
