Answer:
C. I and II
Step-by-step explanation:
The author refers to her car rental services as coming from rent a wreck and she says this to cause some effect to provide humour and sarcasm.
The effect of the author referring to her car rentals as coming from “Rent-A-Wreck” is that it makes the author seem ethical because she does not want to expose a real rental company’s short comings and also suggests that the piece, while being about a serious matter, will take on a humorous or sarcastic tone.
