Answer:
C. Personal selling
Step-by-step explanation:
Personal selling involves the use of sales representatives to persuade customers to buy. The salespersons use their interpersonal and selling skills to convince customers to purchase. They engage customers on a face to face conversation to close a sale.
Personal selling as a promotional technique allows the sales representative and the customer to have a two-way conversation. The salesperson explains to the customer, the features and benefits of the products on sale. He or she tries to make the customer understand the value and advantages of buying the product. The customer gets an opportunity to ask questions on the merchandise and negotiate for a better price.
