Answer:
B.
Step-by-step explanation:
A is more of an appeal to the emotions of the audience; therefore, it is an example of pathos.
C merely presents an opinion on the importance of the decision made by the speaker.
D asks rhetorical questions, and they may be considered to be part of an emotional appeal.
Only B is an example of logos as it provides some facts and statistics and, therefore, uses reason and logic in the attempt to convince the audience.
