Answer:
Legal
Step-by-step explanation:
In literature, the tone is the attitude of a writer or a speaker toward a topic or theme of a piece of writing; it is determined by word-choice, syntax, and the author's writing style. In the sentence provided, the Susan B. Anthony's tone is legal because her idea that women and men are entitled to the same rights is founded on law. Her word choice, such as “constitutions,” “laws of the several states” and “null and void” also shows that her tone is legal.
