The correct option is B Leopold I
The Treaty of Vienna had forced the two regions- Belgium and Holland together. Belgium and Holland had little in common in terms of culture. They had linguistic differences, as well as a deep religious divide. Protestors took to the streets of Brussels, and violent revolts ensued. The Belgians succeeded in getting their demands met, and the independent state of Belgium was created with Brussels as its capital. Leopold I was made "King of the Belgians" in 1831
