I had that same question, its really confusing.
Answer:
In Boston Harbor, a group of Massachusetts colonists disguised as Mohawk Indians board three British tea ships and dump 342 chests of tea into the harbor.
The midnight raid, popularly known as the “Boston Tea Party,” was in protest of the British Parliament’s Tea Act of 1773, a bill designed to save the faltering East India Company by greatly lowering its tea tax and granting it a virtual monopoly on the American tea trade. The low tax allowed the East India Company to undercut even tea smuggled into America by Dutch traders, and many colonists viewed the act as another example of taxation tyranny.
Explanation:
It involved the re-appropriation of Indian land.
The answer is B, increasing political power of free black voters.
