Answer:
The correct option is D.
Step-by-step explanation:
When appealing to the bias of the audience, it is a common tactic to downplay the strength of your opponent. Jones showing her opponent in black and white, looking tired helps to achieve this aim of appealing to the bias of the audience.
Not only does Jones show her opponent as weak, we see that Jones appeared at the end of the ad in full color, looking cheerful, invigorated, and ready to go. This is in stark contrast with the state of her opponent.
This tactic will easily appeal to the bias of the audience and increase support for Jones.
