Answer:
B. He alludes to several positive extremists in history such as Jesus Christ and Thomas Jefferson
Step-by-step explanation:
In his letter from Birmingham Jail, Martin Luther King Jr. used the term "extremist" in a way that was different from the negative connotation that the term often carries. King changed the connotation of the term by alluding to several positive extremists throughout history, such as Jesus Christ and Thomas Jefferson. By doing so, he reframed the term to describe individuals who are passionate and committed to a cause, rather than individuals who are violent or dangerous. King also applied the term to himself and other civil rights activists to show that they were not outsiders, as their opponents claimed, but rather people who were fighting for justice and equality within their own society.
