Answer:
The answer is D: Situational irony is used to highlight the disparity between the expected results of the Emancipation Proclamation and the actual results.
Step-by-step explanation:
Martin Luther King Jr.´s "I have a Dream" speech was delivered in 1963 during the March on Washington for Jobs and Freedom, in an attempt to further the cause against racial discrimination and African American segregation in the United States. In this speech, one of the elements used by Martin Luther King Jr., to further his words, is memory, an appeal to Americans´ historical memory of Abraham Lincoln, the man they admired so much, and who signed during his presidency the Emancipation Proclamation. He also makes reference to the way this historical memory has yet to be seen, yet to be fulfilled. He makes reference to how the dreams of such an important man as Lincoln, especially regarding emancipation, have not been fulfilled because of America´s forgetfullness and unwillingness to work against segregation and discrimination.
