Which of the following is NOT a function of marketing in a business?

In the context of business marketing functions, the emphasis is on activities that directly promote and facilitate the exchange of goods and services to meet customer needs. Product development, market research, and customer service all fall under the umbrella of marketing.

Product development is crucial as it involves creating and refining products based on consumer feedback and market trends, ensuring that offerings are relevant and appealing. Market research is essential for understanding consumer behavior, preferences, and competitive landscapes, which helps shape effective marketing strategies. Customer service plays a significant role in maintaining customer satisfaction and loyalty, essential for repeat business and positive brand perception.

However, financial auditing does not relate to marketing functions. It is primarily a process related to the evaluation of an organization's financial information to ensure accuracy and compliance with regulations. This function falls under finance and accounting rather than marketing, signifying that the correct choice is the one that does not align with marketing's objectives and responsibilities.
