A car dealership promotes cars by donating a percentage of each sale to local charities. A beverage company gives free branded towels to the first 7,000 attendees at a football game. A. differentiated by perception B. differentiated by service C. differentiated by brand name/advertising D. differentiated by quality/design E. differentiated by location

Let's break down these examples:

1. Car Dealership donating a percentage of sales to charities: This falls under C. differentiated by brand name/advertising. The differentiation here lies in the brand's image as socially responsible and caring about the community. It's using its brand image and advertising to create a distinct perception in the minds of consumers.
2. Beverage company giving free branded towels at a football game: This aligns more with C. differentiated by brand name/advertising as well. By distributing branded towels, the company is aiming to increase brand visibility and create a positive association between its product and the enjoyable experience of attending a football game. It's a branding and advertising strategy.

So, both examples primarily fall under the category of differentiation by brand name/advertising, as they focus on enhancing brand perception and visibility through different means.
