The question is asking about one of the principles in marketing goods. The options are Option A: train their personnel, Option B: be consumer oriented (which is the correct answer), Option C: advertise the goods, and Option D: sell through outlets. So, the question is asking which principle is important in marketing goods.

Marketing is the process of identifying, anticipating, and satisfying customer needs and wants through the creation, promotion, and distribution of goods and services. One of the principles of marketing is being consumer-oriented, which means that the needs and wants of the customer should be the primary focus of the company. This principle guides all aspects of the marketing process, from product development to advertising and promotion.

While training personnel, advertising goods, and selling through outlets are all important aspects of marketing, being consumer-oriented is the overarching principle that guides all marketing decisions. It ensures that the company is creating and promoting products that meet the needs and wants of its customers, which ultimately leads to increased sales and customer loyalty.

In summary, the underlying principle in the marketing of goods is being consumer-oriented, which means that the needs and wants of the customer should be the primary focus of the company. This principle guides all aspects of the marketing process and is crucial for the success of any marketing campaign.
