The correct answer is “By citing an example of civil disobedience by everyday people, King shows that civil disobedience can be necessary and productive.”
Indeed, The Boston Tea Party protests are a hallmark of American history equally revered and respected by Northern as well as Southern Americans. This is a very daft strategy since he is associating African American peaceful protesters with the rebellious American revolutionary militants. He is also likening Southern white supremacists to the oppressing British soldiers of the metropolitan monarchy of the UK. In that manner, King is demonstrating that the struggle of African Americans is a struggle in favor of freedom, and against the tyranny of segregation and bigotry of Southern white supremacy.
