Final answer:
Option c, buying a used laptop at a garage sale, would likely be considered the least threat to Cherise's dry cleaning business, as it is unrelated to the competitive dynamics of the dry cleaning industry or online service provision.
Step-by-step explanation:
The question asks which of the following would least likely be considered a threat to Cherise's new dry cleaning business, which uses online services to notify customers about order readiness. Option c, buying a used laptop computer at a garage sale, does not pose a direct threat to the business as it stands outside the dry cleaning industry's competitive dynamics. On the contrary, options a and b highlight racial discrimination and gender discrimination in hiring practices, respectively. These issues might cause public relations harms and legal ramifications but are not directly related to an online dry cleaning business's operational threats. Option d, ordering flowers over the internet for a friend in a different city, illustrates e-commerce but is an activity in a completely different industry, thus posing no threat to the dry cleaning business.
