Answer:
B. Because the tone you use can either draw an audience into your
argument or alienate them.
Step-by-step explanation:
This is the main reason why it is important to set the right tone in an argument. Depending on the tone that you have when presenting an idea, your argument and the essay at large could be more or less persuasive. Moreover, if your tone does not match the subject you are writing about, your writing could look unprofessional. These scenarios could potentially alienate your audience, instead of drawing them into your argument.
