The correct answer is B. If we don't elect Mrs. Smith to the senate, we will definitely see a rise in taxes.
Step-by-step explanation:
In language, the logical fallacy "fear" occurs when the speaker appeals to fear or some situation people are afraid of with the purpose of convincing people about an idea. This means, the speaker does not provide reasons or evidence but relies on the aspects people want to avoid. This occurs in the sentence "If we don't elect Mrs. Smith to the senate, we will definitely see a rise in taxes" because in this case the speaker appeals to the fear of people on more taxes to try to persuade them about not voting for Mrs. Smith; however, this is not a valid argument but is only based on fear.
