Answer:
Option B.
Step-by-step explanation:
In the excerpt, it is possible to notice the speaker's efforts to relate to the audience when he/she states "I bet some of you are doubtful that the advertised thrills could satisfy our teen-aged preferences.". The sentence reveals how the speaker wants to engage with the audience, and not give a monologue that will be hard to relate to. By deviating from his/her narration to open a window to connect with the audience and to acknowledge their presence, the speaker is making his/her narrative more approachable.
