Answer:
C. B2B advertising is concerned with promotion using samples , coupons, and contests.
Step-by-step explanation:
Business to business advertising is a form of sales promotion which occurs between two businesses rather than between a business and consumers. It requires more skills and efforts as the target audience are usually the workers in the other organization. For example, a company that produces school uniforms, might take some samples of their products to a school while advertising.
A business employing this sort of advertising wants to promote its services or products to another organization. They could employ the use of samples, and coupons to make the marketing more effective.
