Final answer:
The Stakeholder Theory Moral Standard is most aligned with the argument that the new store will benefit the community by saving money for customers and creating jobs.
Step-by-step explanation:
The moral standard of social responsibility that best fits the business's argument in the context of Vivian's company considering building a huge new department store in a small town is the Stakeholder Theory Moral Standard. This theory suggests that companies should balance the interests of all stakeholders, including employees, customers, and the community at large, rather than focusing solely on profit-maximization or shareholder interests. Vivian's argument suggests that the company acknowledges its broader social responsibilities by emphasizing potential benefits such as cost savings for customers and job creation in the community, which aligns with the Stakeholder Theory.
