Which of the following are exclusively functions of marketing?

The correct answer is: "Buying, pricing, selling, and promotion". These four activities are the core functions of marketing. Buying refers to the process of selecting products and suppliers, while pricing involves setting the right price for the product to ensure profitability and competitiveness. Selling is the process of persuading customers to buy the product, and promotion involves communicating the benefits of the product to potential customers through advertising, public relations, and other promotional activities. While activities such as risk-bearing, storage, production, transporting, and recruiting are important to the overall success of a business, they are not exclusive functions of marketing.
