Final answer:
The Sons of Liberty initiated the Boston Tea Party in direct response to Taxation without representation.
Step-by-step explanation:
The Sons of Liberty initiated the Boston Tea Party in direct response to A) Taxation without representation.
The British Parliament passed the Tea Act of 1773, which allowed the British East India Company to sell tea to the American colonies without paying taxes. This made the company's tea cheaper than that sold by colonial merchants. The Sons of Liberty, led by Samuel Adams, saw this as another example of taxation without representation and staged the Boston Tea Party to protest against it.
