The independence movement in Brazil was unique in South America because it resulted in a constitutional monarchy. The correct option is (C).
On September 7, 1822, Brazil proclaimed its independence after travelling a really unconventional route. It began as a traditional colony and developed into the capital of the Portuguese empire by 1808 before being elevated to the rank of a kingdom (equivalent to Portugal) in 1815.
The Portuguese regent in Brazil, who later rose to the position of emperor, announced and oversaw Brazil's independence, setting it apart from that of the rest of Latin America.
Brazil's Independence was the result of a string of political and military developments that separated the Kingdom of Brazil from the United Kingdom.
Therefore, the independence movement in Brazil was unique in South America because it resulted in a constitutional monarchy.
