Answer:
B. By using the rhetorical question to explain the objection to his movement, MLK refutes the opposition by providing explicit reasons for their dissatisfaction in order to legitimize his movement and motivate his audience to continue fighting for their right.
Step-by-step explanation:
Option B is the correct answer.
This option provides the best analysis for Martin Luther King's rhetorical question "When will you be satisfied".
In the "I Have A Dream" speech by Martin Luther King Jnr., we see King asking the question, "When will you be satisfied". This he reveals in his speech that "There are those who are asking the devotees of civil rights, when will you be satisfied?"
So, he repeats the question of those people and goes ahead to refute their opposition. He does that by providing explicit reasons for their dissatisfaction.
