Answer:
D. Brazil was a Portuguese colony, and the King of Portugal fled to Rio de Janeiro after Napoleon conquered Portugal where he remained even after Napoleon’s defeat.
Step-by-step explanation:
The reason Brazil has such a significant Portuguese influence is due to "Brazil was a Portuguese colony, and the King of Portugal fled to Rio de Janeiro after Napoleon conquered Portugal where he remained even after Napoleon’s defeat."
This is evident in the fact that Portugal colonized Brazil between the 1500s till 1822 when Brazil became independent.
Also, during the Napoleonic invasion of Portugal, King John VI of Portugal organized his court in Brazil and has a representative government in both Portugal and Brazil.
