Answer:
b. Sales promotion
Step-by-step explanation:
Sale promotions are activities that a company engages in to persuade a potential customer to buy its products. Sale promotions are short-term tactics to boost sales. Although a business may get long-term customers through sales promotions, there are designed to entice new customers in the short-run.
Sales promotions encourage customers to switch brands or try out a different product. They are ideal when introducing new products in the market. Howerver, they are costly, and sometimes have a short term effect on sales.
