The correct answer is - B. Latin American leaders demanded independence.
Napoleon with his conquests and waging wars managed to weaken lot of countries. One of those countries was Spain. Spain already seemed to have troubles in its colonies, and when Napoleon attacked it, he managed to significantly weaken it, which sparked the independence movements across Latin America.
The Latin American leaders were carefully monitoring the development of the situation, and once they thought that Spain is no longer strong enough to be able to stop the revolutions, they decided to act. The people were already very frustrated by the Spanish leadership, so the leaders of this region used that momentum and started to make revolutions. One by one, the Latin American countries started to gain independence, some sooner than others, and it really turned out that Spain was not able to oppose all of them.
