Answer: D) impassioned.
Step-by-step explanation: the tone of a poem, story or text is the author's or speaker's attitude towards the audience, the subject or even a character in the text. There are many different kinds of tones, like, happy, sad, negative, positive, angry, etc. In the given excerpt from "My Bondage and My Freedom" by Frederick Douglass we can see that the speaker's tone toward freedom is impassioned, he shows excitement and emotion toward that subject.
