Explanation
The Appeal to Emotions is a persuasive resource that uses language to convince someone of the truth of a fact by manipulating their emotions, without any logical reasoning. This resource is very effective in getting the audience to favor what the speaker is saying because it moves the public's will to achieve a goal or to make a decision. According to the above, President Lincoln resorted to the appeal to the emotional because he uses phrases such as "We must not be enemies. Though passion may have strained it must not break our bonds of affection". So the correct answer is A. Emotional Appeal.
