Answer:
A). She cites a personal services company in another city that increased its business by adding dog walking to its services.
Step-by-step explanation:
PREP method is demonstrated as the effective method or approach of presentation or speech that consists of four steps: 'P stands for 'point'(statement of claim), 'R stands for 'reasons'(explanation of the point), 'E stands for 'examples or evidence'(to support the claim), and lastly, 'P stands for point('justification and restatement of the claim').
According to this method, option A i.e. 'She cites a personal services company in another city that increased its business by adding dog walking to its services' reflects the third step that Khandi uses for her presentation. This citation would not only support her claim but also establish the credibility of her claim while the next step would prove how her claim is justified. Thus, option A is the correct answer.
