The correct answer is: A. marketing concept
The marketing concept is a business philosophy that focuses on satisfying customer needs and wants as a means of achieving organizational goals. It is a customer-oriented approach to business that emphasizes the importance of understanding and meeting the needs of customers.
A single, integrated information system can help businesses to better understand their customers and their needs. By collecting and analyzing data from a variety of sources, businesses can gain insights into customer behavior and preferences. This information can then be used to develop products and services that are more likely to meet the needs of customers.
The marketing concept is not the only way to achieve a single, integrated information system. However, it is a valuable approach that can help businesses to better understand their customers and their needs.
The marketing mix is a framework that helps businesses to develop and implement marketing strategies. It consists of four elements: product, price, place, and promotion.
The marketing grid is a tool that helps businesses to segment their markets and develop marketing strategies for each segment.
The marketing matrix is a tool that helps businesses to allocate their marketing resources across different products and markets.
None of these options are as closely related to the attainment of a single, integrated information system as the marketing concept.
