Complete answer:
Britain was in deep debt in the 1760s, so a series of taxes were inflicted on American colonists by the British parliament to help pay those debts. According to the British government, the taxes were fair because a large amount of its debt was earned fighting wars on the colonists’ behalf. However, this act was disagreed by the colonists and they were enraged at being highly taxed without being represented in the parliament and felt unfavourable for being imposed on themselves to gain revenue. The objective was the Tea Act of 10 May 1773, which permitted the British East India Company to sell tea from China to the American colonies without paying taxes outside those imposed by the Townshend Acts.
The taxes in the Townshend act were strongly opposed as a violation for their rights by the American patriots. Demonstrators, sometimes dressed as Amerindians, destroyed an entire cargo of tea sent by the East India Company. The ships were boarded and the chest was thrown into Boston Harbor. The UK government reacted harshly and the episode intensified until the American Revolution.
The Tea Party resulted in a resistance movement across British America against the Tea Act, passed by the British Parliament in 1773. The tea act was opposed by the colonists because they considered it as a violation of their rights as Englishmen to no taxation without being represented, which means they are being taxed only by their own elected spokesperson and not by the British parliament.

Therefore, option A is the right answer.

Note: The British government repealed the stamp act and introduced the Declaratory Act for reaffirming the power of the parliament.
