Which of these businesses is the best candidate for mass marketing?

a. a local doctors office
b. a local smoothie store
c. a national craft supply store
d. a national ice hockey equipment store

Out of the given options, the best candidate for mass marketing would be (c) a national craft supply store.

A local doctors office and a local smoothie store are not likely to benefit from mass marketing as they primarily cater to a limited local customer base. Mass marketing would be less effective and highly costly for these types of businesses, as it would reach a large number of people who are not within their target market.

On the other hand, a national craft supply store can benefit from mass marketing as it targets a larger audience nationwide. Mass marketing strategies such as TV commercials, online ads, and nationwide promotions would help reach a wider customer base and increase brand awareness.

Similarly, a national ice hockey equipment store would also benefit from mass marketing as it targets ice hockey players and enthusiasts across the entire country. Employing mass marketing methods like television ads, online campaigns, and sponsorships at national ice hockey events would be effective in reaching a wider audience and generating sales.
